An emoticon that represents an asian person crying. The top of the T's are eye slits and the stem of the T are tears streaming out. The period is of course the nose.
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 gets lucky and kills all of Players A's units while Player A does not noticed>
Player A: T.T
Player B: Yeah, I can't believe you didn't see me.
Occasionally people will respond with this emote to some of your more precariously aimed remarks.
Is translated to and can be interpreted as a thanking; thank you.
More Ts can be added by the other person to extend or increase the amount of thanking that you receive.
Replying with "yw" is perfectly appropriate.
Short for Twirl & Thanks or Thanks & Twirl (like brb). Can be uppercase (T&T) or lowercase (t&t), even with a n (TNT, tnt, TnT). To sashay away and see you later, and may or may not include a hair flip.
The drag queen grabbed the dollar and said "T&T mon ami !" Then continued to proceed back to the stage.
