Teen 1: Hey girl!
Teen 2: Hey girrrrlllll! You coming to the party?? Jake will be there. I heard he wants to see you ;)
Teen 1: You know it!! ;)
Teen 2: Okay girl, tmw your on the way!! ;D

touch my wang. most often used after nights without any 'action,' likely used in IRC channels, and directed toward fellow channel-goers. this acronym can have disasterous effects as it can rouse the homo-hater in many. can also be used in response to aboslutely anything.
