Answer:
QQ originates from Starcraft, where the control for exiting the game was Control + Q + Q, so when raging, people would quit the game by "QQing", Coincidentally, QQ, Q_Q, and Q.Q look like eyes with tears in them, so the original meaning has been forgotten and is now thought to have to do with "crying more" or to "quit crying". qq much? oh! pwned!
