A "QQ thread" in the discussion forums of MMORPGs like World of Warcraft, is where a user starts a discussion thread which is basically a complaint, whine or whinge about something in the game they are not happy with.

QQ itself is meant to symbolise someone crying; the Qs looking like eyes with tears streaming from them.
"This isn't a QQ thread, but please nerf class X as they beat me in combat and thus must be overpowered and imbalanced!"
