The person who makes and sells tacos at a street stand or taquería in Mexico. A taquero is a respected figure in Mexican food culture, the one who skillfully handles the grill, chops the meat, and assembles your tacos at lightning speed while managing dozens of orders at once. A good taquero is worth their weight in gold.

A tip left for a waiter or service worker on top of the bill. In Mexico, tipping is an important social custom: 10% is the bare minimum, while 15 to 20% is what considerate people leave. Skipping the propina is a real social offense, since waitstaff depend on it.

A rallying chant fans use to motivate their team when they're losing or need a goal. Literally 'yes we can,' it's the mantra of the Latin American stadium, the chorus that says there's still hope and the scoreboard can still flip. Cesar Chavez also adopted it as a labor rights slogan in the US.

A direct expression for telling someone you're romantically or physically attracted to them, equivalent to 'I like you' in English. It's the first big step in confessing interest, before going as far as 'te quiero' (I care about you) or 'te amo' (I love you). Saying it out loud takes guts.

To sneak glances at someone you find attractive without making it obvious. Like "checking someone out" but more discreet and street-level. Common in Mexico.

Absolutely yes, of course, definitely, the most emphatic affirmation in Mexican slang. 'A güevo' closes the discussion: you're going, you're doing it, it's happening. No conditions, no hesitation. The word is direct to the point of being blunt, and that's exactly the point.

To turn someone on, to sexually arouse or attract them, either intentionally or just by existing. Used across Argentina, Uruguay, Mexico, and Spain in a casual and direct way.
