In online game speak, usually refers to "quit crying noob" or "cry more noob". The QQ is an old chat emoticon for a person crying. Seen predominantly in online gaming where one side starts complaining immediately upon ending a match, or one who constantly complains. QQNOOB is sometimes used as a curt response on web forums as well when someone spends an inordinate amount of time complaining about a subject.
