To keep watch, act as a lookout, warn the group if someone is coming. In Mexico echar aguas is the essential role in any mischief — you're the one watching the door.

Someone who got a job, privilege or position through connections rather than merit. In Mexico and Spain an enchufado is plugged in — it's not what you know but who you know.

A fool, a goofy person who makes themselves look ridiculous without realizing it. In Central America a ganso is well-meaning but socially clueless — everyone's laughing but they don't know why.

A decisive response or action that leaves someone speechless and without arguments. A strong comeback is worth more than ten insults.
