A chaleco

What it means

You did it and you did not want to. Somebody decided, the rule required it, the situation left no room - and the phrase attaches to the doing rather than to the decider.

The tone is resigned rather than furious. It is what somebody says about a mandatory Saturday, a family obligation, or a form that had to be filed, and it usually arrives with a shrug rather than a complaint.

Literal meaning

Un chaleco is a vest, and how a vest came to mean under duress is not established - the origin stories in circulation are guesses. The garment itself has a perfectly documented history, arriving in Spanish from Algerian Arabic and Turkish for a sleeveless jacket; it is only the jump to compulsion that nobody can account for.

The phrase itself is well recorded, which is worth separating from the origin. Both the Diccionario del español de México and the pan-American dictionary carry a chaleco as por la fuerza. What the dictionaries do not carry is much of a family around it: the Diccionario del español de México has no entry for chalequear at all, and the pan-American dictionary marks that verb for Colombia, Venezuela, Peru and the Southern Cone rather than for Mexico.

The company it keeps is the useful part. Mexican Spanish has a small set of compulsion phrases - a huevo, a fuerzas, de a fuerza, a la mala, quieras o no, por obligación - and they swap into most sentences, differing in register and in how many other jobs each one does.

How Mexicans use it

The commonest form attaches to a verb: tuve que ir a chaleco, me hicieron firmar a chaleco. The phrase modifies the action and leaves whoever imposed it unnamed, which is often the diplomatic point.

It also works as a bare answer. ¿Y fuiste? A chaleco. Two words, and the whole story is that somebody else decided.

A chaleco que introduces a prediction about something unavoidable - a chaleco que nos toca quedarnos. It exists and it is worth recognizing, though a huevo que is far more common in that construction.

In work chat it softens a complaint about a decision from above, because it does not name the person who made it. That vagueness is useful and it is why the phrase turns up in writing more than most slang.

Common mistake

Reaching for a huevo when you mean this. A huevo is the more famous phrase and it is genuinely ambiguous - said brightly it means absolutely, said flatly it means by force. If the room might read it the wrong way, a chaleco removes the doubt.

Assuming it is rude because it sounds like slang. It is mild, it is safe in an office, and a fuerzas is the plainer version if you want to be certain.
