Quick Answer
Aguas means heads up or watch out in Mexican Spanish.
- Use it when someone is about to trip, miss something, or get caught by surprise.
- It is casual, useful, and not offensive.
What it means
Aguas is a quick warning. It means heads up, careful, or watch out, usually when something is happening right now.
It can be serious or playful. Someone can shout it before you step into a pothole, or whisper it when the boss walks into the room.
Literal meaning
Literally, aguas means waters. The plural sounds strange until you know the old story behind it.
In colonial cities people shouted before throwing dirty water out a window - agua va is a dictionary entry for exactly that. Whether Mexico's aguas came straight from that shout has never been shown, but it is the story everyone tells.
How Mexicans use it
Mexicans use aguas as a fast alert. It works before a physical danger, a social risk, or a small surprise.
You will hear aguas con... before the thing you should watch out for: aguas con el escalón, aguas con el perro, aguas con tu jefe.
In texts and group chats it shows up as a heads-up too - 'aguas, hay retén en Insurgentes' or 'aguas con ese link' - a quick way to flag a risk to friends.
Examples
- ¡Aguas con el escalón!Watch out for the step!
- Aguas, ahí viene el jefe.Heads up, the boss is coming.
- ¡Aguas, se te va a caer la salsa!Careful, you are about to drop the salsa!
Mini dialogue
Common mistake
The common mistake is translating it as water. In slang, aguas is almost never about actual water.
Another mistake is using it after the danger has passed. Aguas works best right before the thing happens.
Don't sound gringo
one of the safest words here. you can shout it at a stranger about to step into traffic and it lands as helpful.
Pair it with con to name the danger: aguas con el escalón, aguas con tu cartera. That small con is what makes it sound like you have lived here rather than looked it up.
