Got to Go.

See gtg

Internet persona(s) who happens to follow you and you happen to follow them back and maintain communication with and have a mutual liking for eachother whether it be friendship wise, etc. (Mutuals if more than one mutual)

Means got to go, though i don't see why someone can't just type got to go. Damn lazy youth.

this means: got to go

what an asshole online says when you just got to the good part of the conversation. They say g2g and you get PISSED OFF because you don't have anything better to do, and your friend that just said g2g is probably going to wack off or something...

an easy way of getting rid of that boring person on msn
instead of making up a lame excuse u just say g2g
and then talk 2 your other friends!!!
