or QQ [kyoo-kyoo]
What does qq mean?
Qq is an emoticon that represents “crying.”
In the gaming community, it is used as a taunt against players seen as unskilled or weak. Elsewhere online, qq variously denotes sadness, loss, or “crying.”
Where does qq come from?
Among gamers, qq can represent the act of crying or feelings of sadness upon defeat, and it’s usually issued as an insult or taunt.
Qq is thought to come from that the fact that its capital form, QQ, resembles eyes shedding tears, similar to other emoticons such as :'( or T-T.
Another theory, however, claims qq originated from players of the 1995–96 computer game Warcraft II: Tides of Darkness by Blizzard Entertainment.
In that game, a player could quit a game, as out of rage or frustration, with a keyboard shortcut: holding the Ctrl key and hitting the Q key (quit) twice. Because of this, more expert players would ridicule their less skilled counterparts (noobs) by advising them to qq, or quit the game.
Many other popular games made by Blizzard, such as Diablo (1996) and Starcraft (1998), featured a similar keyboard shortcut.

Evidence for qq appears on Usenet forms and Urban Dictionary in 2006, nearly a decade after these games were first released. However, qq is discussed—and credited to—the Warcraft series. In gift bags given out at its BlizzCon gaming convention 2008, Blizzard Entertainment featured tissues printed with the phrase QQ n00b, further embedding qq in the Warcraft community.

Who uses qq?
For non-gamers, qq or QQ is treated like crying eyes emoticons, often standing in for the word “cry”, or otherwise used to express loss, defeat, or sadness.
Among gamers, qq or QQ is likewise used as a synonym for “cry,” although in gaming contexts it’s typically used in ridicule, e.g., go qq, loser.
