"Tough titty says the kitty but the milks still good"..meaning tough.
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!
The meaning is smth about t(ears)t(ears).
These "smileys" are often seen in games(warcraft3,wow etc.) but they are also visible in the public forums, mirc, msn, icq ,email etc.
It can also be used as a normal ":)"-smiley for funny things.
This smiley has lost the meaning in the real meaning to mean smth is sorrow.
