The shortened word it self, 'TT', was created by the YouTube and Internet sensation, ShayCarl, who was first to refer to the pod, of truckular variety, as a 'TT'. He created the word after realizing early in his daily Internet vlogs, that it was both difficult to steady a video camera whilst trucking, and could even be dangerous. Despite this, to this very day, Shay does not own a TT, a shocking revelation to the perils that may lie ahead for Shay whilst trucking, and vloging, at the same time.
ShayCarl Again: Oh gees! This truck is really shaking at this speed, nearly doped you guys in my truck, 'My manly truck!'. I think it's definitely time for a TT. What do you guys think, I don't know, leave it in the comments below, OKAY BYE!
This is commonly used in online games (such as Warcraft) by a player when something goes very badly or unlucky for that player.

Player B: Yeah, I can't believe you didn't see me.
