Meaning of DQN

DQN is “Bad people” or like a rogue. Imagine the people who are crazy, foolish, stupit and loose cannon… they are “DQN”.
“DQN” has only bad image, so if someone say “He is DQN” someone hate him.

It’s a internet slang, but most of young people know this meaning. This pronunciation is “do-kyu-n”.

I didn’t know the origin of this word. So I googled it.
The origin of “DQN” is a TV program “目撃!ドキュン” (this pronunciation is “mokugeki-do-kyu-n”). And in the TV program, there were many DQN. (I haven’t watched this, so I don’t know detail.)
