STT stands for stop to text and it is when someone pulls over on the side of the road to send a text message.
I had to STT to tell Ramone about the Strawberry Shortcake I gave the girl from the club last night.
Safe to talk.
Used when parents or unsavory authority-types might be around.
personuno: hey, stt?
personuno: k, so neway he had this needledick...
