TUI

What does TUI stand for?

Turning you in

TUI is a nark's favorite acronym. It stands for "turning you in," which an informant or tattle tale will do when you do something wrong.

A person may use TUI seriously or jokingly when messaging online or via texts. For example, your sister may have discovered your stash of illegal fireworks and might threaten TUI to the rents if you don't do something for her. Or, your friend may joke about TUI when you admit that you cheated on the Geography quiz.

Example

Please don't cheat on the test. I don't want to have to be TUI!
