TUI: Texting Under the Influence.

Getting the bright idea to text ex-girl/boyfriends, parents, siblings and enemies expecting them to enjoy your thoughts while intoxicated. This especially occurs after a game of beer pong or round of shots, during a lonely cigarette at or around 4am
"I cam this close to a TUI last night, good thing my mom doesn't know how to text!"
