The Complete Guide to Mexico City Spanish Slang (CDMX Dialect)

Mexico City Spanish is its own thing. Chilangos (CDMX locals) speak fast, use heavy slang, and borrow from Náhuatl in ways that no app ever prepared you for.

I know because I moved there speaking what I thought was decent Spanish, enough to get by, I thought. Two weeks in, I realized I couldn’t follow a single conversation at the taquería counter without asking people to repeat themselves three times.

This guide is the result of two years on CDMX streets, markets, and conversations. These are phrases that actually come up, with context on when to use them, when not to, and why.

The Essentials You Can’t Go Without

¿Qué onda?

Forget ¿Cómo estás?. Nobody says that on the street. ¿Qué onda? is the default casual greeting. Literally “what’s the wave?” but functionally: “what’s up?” or “how’s it going?”

You’ll hear it dozens of times a day. Use it freely with anyone you’re on familiar terms with. Don’t use it with a police officer or your landlord’s grandmother.

Pronunciation note: The qu- in qué is a hard “K” sound. QUÉ ON-da. The onda rhymes with “Honda.”

Güey (or wey)

This is the most-used word in Mexican Spanish, full stop. Roughly equivalent to “dude” or “man,” used between friends, with vendors you know, with basically anyone in a casual context.

Technically it started as an insult (long story involving castrated bulls). But it has completely lost that meaning in everyday use. Between friends it’s neutral to affectionate. Said to a stranger, it’s still a bit blunt.

Spelling tip: You’ll see it written as both güey and wey. Both are correct. The pronunciation is the same: “way.”

No manches / No mames

No manches is the PG version. No mames is the R-rated version. Both mean something between “no way,” “you’re kidding me,” and a certain English expletive.

No manches is fine in any casual context. No mames you should know to understand locals, but use it carefully until you know the register.

Chido / Chida

“Cool,” “great,” “awesome.” Used constantly. Está chido: that’s cool. Qué chido: how cool. Es muy chida: it’s really great (feminine noun).

Neta

“Truth” or “for real.” La neta = the honest truth. ¿Neta? = “Really? Seriously?” You’ll hear this one everywhere.

At the Taquería

This is where a lot of people freeze up. The pace is fast, the cook is busy, and the order isn’t always obvious.

¿Qué le pongo? / ¿Qué se le ofrece?

What the cook says: “What can I get you?” Both phrases mean roughly the same thing. ¿Qué se le ofrece? is slightly more formal.

What you say back: Name your taco filling and number. “Dos de pastor, uno de suadero.” No need for por favor at every sentence; it slows things down and sounds odd at a fast-moving counter.

Al gusto

“To your taste.” When they ask ¿con todo? (with everything) and you say al gusto, you’re saying “however you recommend it.” Works fine for tourists, but as you get more familiar you’ll want to specify: sin cilantro, con todo lo demás (no cilantro, everything else).

Un kilo de tortillas / Medio kilo

At tortillerías, you order by weight. Un kilo is roughly 12-15 tortillas. If you’re cooking for two for a few days, un kilo is right.

At Markets (Mercados)

¿A cómo?

“How much?” Efficient and direct. Standard when you want the price of something at a market stall.

¿Me da…?

“Can you give me…?” This is the polite standard for ordering/requesting at a market. ¿Me da un kilo de jitomate? (Can I get a kilo of tomatoes?) More polite and natural than quiero (I want).

Le dejo en…

“I’ll let you have it for…” This is what vendors say when they’re offering you a price. Common in negotiation.

¿Le late?

“Does that work for you?” A casual way to confirm a deal. Te lo dejo en cien. ¿Le late? (I’ll give it to you for a hundred. Sound good?)

Money Slang

Mexico City has its own vocabulary for cash, from the market stall to splitting a bill.

Lana: “money,” casual and universal. No tengo lana (I’m broke). Heard from taxi drivers, coworkers, and friends alike.

Varo: another word for money, a notch more slang than lana. Ando bien apretado de varo este mes (I’m tight on cash this month).

Feria: small change or cash on hand. ¿Traes feria? (Got any cash on you?) At a market stall it often means coins or small bills.

Andar bruja / Andar quebrado: both mean “to be broke.” Andar bruja (literally “to be a witch”) skews younger; andar quebrado works across generations.

Pagar a medias: to split the bill. ¿Pagamos a medias? (Should we split it?)

Everyday Mexican Vocabulary You Won’t Learn in a Spain-Based Course

Mexico City’s Spanish includes words that no Spain-based textbook covers. Some are Náhuatl loanwords; others are just Mexican vocabulary that diverged from Spain Spanish over five centuries.

Jitomate is the big one. If you ask for tomate in CDMX, you’ll get the small green tomatillo. If you want the red tomato, say jitomate.

Only jitomate in this list is actually Náhuatl-derived (from xitomatl). The others are standard Mexican Spanish that diverges from what Spain-based textbooks teach. Náhuatl loanwords that do show up constantly in everyday CDMX speech include: aguacate, elote, chapulín, chayote, cuate, tianguis, and chile itself.

Workplace and Office Slang

Whether you’re in an office or freelancing, this vocabulary shows up in every meeting and group chat.

Chamba: “job” or “work,” used far more than the textbook trabajo. Ando buscando chamba (I’m job hunting). It’s where chambear, “to work,” comes from.

Jefe / Jefa: literally “boss,” but also used affectionately for one’s parents. Mi jefa can mean “my mom,” not just “my boss.”

Checar: “to check,” borrowed from English. Voy a checar mi correo (I’m going to check my email).

Junta: “meeting.” Tengo junta a las diez (I have a meeting at ten).

De volada: “right away.” Lo hago de volada (I’ll get it done right away).

Buena onda / Mala onda: office culture shorthand. Buena onda describes someone easygoing and likeable; mala onda is the opposite, someone difficult, or just a rough situation. Qué mala onda que te cancelaron la junta (that’s a bummer they cancelled your meeting).

Dating and Relationship Slang

Ligar: “to flirt” or “to hook up with,” in the sense of meeting someone new. Fue a ligar al bar (he went to the bar to try to meet someone).

Andar con alguien: “to be seeing someone.” Ando con Fer desde hace dos meses (I’ve been with Fer for two months). More casual than salir con alguien.

Amigovio / Amigovia: a blend of amigo (friend) and novio (boyfriend). The closest equivalent to a situationship.

Caerle bien / Caerle mal: literally “to fall well or badly on someone,” meaning “to like or dislike” a person, not romantically. Me cae muy bien tu amigo (I really like your friend).

Echar la onda: to hit on someone, more subtle than ligar. Le está echando la onda desde la fiesta (he’s been hitting on her since the party).

Dejar plantado / plantada: to stand someone up. Me dejó plantada (he stood me up).

Texting and WhatsApp Slang

Most day to day communication in CDMX happens over WhatsApp, with its own shorthand no classroom teaches.

Xq: short for porque (because) or por qué (why), depending on context.

Tqm: te quiero mucho (I love or like you a lot), used between friends and family too.

Nmms: short for no mames, typed fast in group chats.

Jsjsjs / Ksksks: the Mexican equivalent of “lol.” The letter j makes an “h” sound in Spanish, so typing jsjsjs mimics a breathless, exaggerated laugh.

Ahorita: technically means “right now,” functionally means anywhere from five minutes to never. Ahorita voy (I’m coming, eventually). One of the most misleading words for learners, since it depends entirely on tone.

Porfa: short for por favor (please), used constantly in texting and speech.

Nel: casual “no,” blunter than no.

Simón: a joking “yes,” the way an English speaker might say “yup.”

Transport Vocabulary

CDMX has its own transport ecosystem with vocabulary that doesn’t translate directly.

Metro / Sistema de Transporte Colectivo: the subway system. Just call it “el metro.”

Metrobús: the bus rapid transit (BRT) system. Separate from regular buses, has dedicated lanes.

Camión: city bus. Generic term for any bus.

Pesero / Combi: smaller shared minivans that run fixed routes. Cheap and fast but confusing to navigate at first.

Uber / DiDi: both are widely used in CDMX. Safer than hailing random taxis, especially at night.

Está cañón el tráfico: “traffic is brutal.” Cañón means “intense” here. You’ll hear this constantly near Reforma at rush hour.

Se me ponchó una llanta: “I got a flat tire.” Worth knowing if you drive, or if a pesero breaks down mid route.

Bájese en la esquina: “get off at the corner.” Useful for peseros and combis, which don’t always have marked stops.

Insults: Affectionate Between Friends, Fighting Words With Strangers

Mexican insults work differently depending on who’s saying them. Between close friends, certain words are terms of endearment. Said to a stranger, the same word is something you don’t walk back easily.

Pendejo: the most common Mexican insult, roughly “idiot” or “fool.” Between friends, tossed mid-joke, it barely registers: No seas pendejo, ven aquí (don’t be an idiot, come here). Directed at a stranger with heat behind it, it’s genuinely offensive.

Cabrón: even more flexible. Among friends it can mean “tough” or “impressive,” or just stand in for güey: Está cabrón ese examen (that exam is brutal). To a stranger, it’s a serious insult.

Pinche: an all-purpose intensifier, closer to “damn” than a standalone insult. Pinche tráfico (damn traffic), pinche calor (this damn heat). Mild almost everywhere, but not for your landlord’s grandmother.

Naco / Naca: a classist insult meaning “tacky” or “low class,” aimed at how someone dresses or carries themselves. Unlike pendejo or cabrón, this one rarely flips affectionate.

Verga (and its compounds): vulgar and extremely common. Me vale verga (I couldn’t care less), qué verga (what the hell). Tone matters more than the word itself.

Words That Will Get You in Trouble

Some words common in Spain are vulgar or offensive in Mexico. The big one:

Coger: In Spain, this means “to take” or “to grab” (perfectly innocent). In Mexico, it means “to have sex.” Do not say voy a coger el camión (I’m going to take the bus) in Mexico. Say tomar el camión or agarrar el camión.

Similarly, tío/tía is used naturally in Spain to mean “guy/girl” but sounds foreign and odd in CDMX. Mexicans say güey, mano, carnal, or just the person’s name.

The Sounds of CDMX Spanish

Mexico City Spanish has a distinctive sound profile compared to other Spanish dialects.

Vowels are clear and consistent. Unlike Caribbean Spanish (Cuban, Puerto Rican), which drops syllables and blends sounds, Mexican Spanish, especially CDMX, is notably clear. Each syllable is pronounced. This actually makes it one of the easier dialects for learners.

The “s” at the end of words is pronounced. In many Spanish dialects, final “s” sounds get swallowed. In CDMX it’s typically clear. Más sounds like más, not má.

Double “l” (ll) and “y” both sound like “y.” Calle (street) sounds like ca-yeh, not ca-she as in Argentina.

How Slang Shifts by Neighborhood and Generation

CDMX slang isn’t one uniform dialect. It shifts depending on who’s talking and where.

Fresa: a preppy, upper class style of speaking, associated with Polanco, parts of Condesa, and the south of the city. A fresa accent softens slang and mixes in English. Applied to someone outside that circle trying too hard, it’s not a compliment.

In neighborhoods like Iztapalapa and Doctores, slang leans harder into the classics: heavy güey, chido, and neta, plus cabrón and pendejo in their affectionate sense.

Generationally, younger Chilangos mix in more English than their parents did. Words like “cringe” and ghostear (to ghost someone) drop straight into Spanish sentences, alongside shorthand like jsjsjs. Older speakers lean more on classic slang and Náhuatl-rooted vocabulary.

None of this means there’s a “correct” version to memorize. Chilangos code switch constantly depending on who they’re talking to: a taco vendor, a coworker, their grandmother. The more you listen, the faster you’ll pick up which register fits which situation.
