To act snobby, bougie, or pretentious. In Mexico, it comes from "fresa" which means a posh, stuck up person, so fresearse is the act of putting on airs, acting like you're too good for something, or suddenly adopting upper class mannerisms. It's often used when someone starts acting fancy out of nowhere.

Someone bold, daring, or gutsy who doesn't hesitate to take risks or speak their mind. In Mexico, calling someone aventado is usually a compliment, meaning they've got nerve and aren't afraid to go for it. It can also mean reckless depending on context, like a driver who cuts through traffic without caring.

Red tomato in Mexico — the Nahuatl word that distinguishes it from the green 'tomate' (tomatillo). In most of the Spanish-speaking world there's only one 'tomate,' but Mexico needs two words.

Someone who's crazy, unhinged, or has a screw loose. In Mexico and Argentina, it describes a person who does wild, irrational things or says outrageous stuff without any filter. It literally means "unhinged" or "loosened," like a bolt that came undone in someone's head.
