Dude, mate, guy. "Tía" for a woman.
The Spanish equivalent of güey or parce. Opens sentences, closes them, and fills gaps: "tío, no te lo vas a creer." Unlike Chile's weón or Argentina's boludo, tío has no insulting edge — it is just informal.
Literally "uncle." The family word got extended to any peer, the way "bro" did in English.
In Latin America "tío" only ever means uncle. Use it as "dude" in Bogotá and people will look for your uncle.
Mexico says güey, Colombia says parce, Argentina says boludo, Chile says weón.
Reading a definition isn't the same as saying it to someone. Lingo Kaiava is a voice tutor set to Spanish (Spain) Spanish — it uses tío the way locals do, corrects you in the moment, and never "fixes" the way real people actually talk into textbook Spanish (Spain) Spanish.
