What does TUI stand for?

Turning you in

TUI is a slang term loved by informants and tattle tales. It’s an acronym for the phrase “turning you in”, which is what someone might do if they catch you doing something you shouldn’t.

This term can be used both in a serious manner or in a playful way during online chats or text messages. For instance, your brother may stumble upon your hidden collection of forbidden candy bars and could threaten to TUI to your parents unless you do a favor for him.

Or, it could be your classmate poking fun at you with a TUI threat when you confess that you peeked at the answers during the Math test.
