A way of saying "one thicc boi". The "un" is the masculine indefinite article, meaning "a", from the Spanish language. "Thicc boi" is from the English language, and when combining these two phrases, makes a Spanglish sentence. This is a better way to say "one thicc boi" and is, from experience, more likely to get laughs. Sometimes you can say "un hella thicc boi" but that can be a bit over the top.

He's a really nice guy until your good friends with him, then he's an asshole. He's definitly not a theater kid. And he doesn't use Italian cologne.
