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.

Tone and safety:
- Aguas is safe and normal. It is informal, but it is not vulgar.
- If the situation is formal, cuidado is cleaner. In real life, aguas sounds faster and more Mexican.

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.

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:
A: ¡Aguas, ahí va el bache!
