I did it for the lulz.

Is the best response when being asked, "Why did you do it?"
Lulz being a corruption of "lol" deriving from the Chan network.

If you're in a live chat with someone get it set in your mind that you want that person DEAD and then type that phrase (I did it for the lulz) 3 times into the chat window then Smiley will appear behind that person and KILL THEM live on cam while you watch.

When you do whatever you want, when you want, because you can. And you do it with pleasure. It's an epic thing, just epic.
LULZ is seen as a God, it just is.

A phrase used in the highly successful movie Smiley where the character would type the phrase into HideandGoChat video call typing"i did it for the lulz" 3 times in which the person on the other end of the call is game ended

The catch-all excuse for the denizens at Encylopedia Dramatica to be as racist, sexist, anti-semitic, and any other form of bigotry as they want to be and turn their page into the Stormfront wiki.

If you are on video chat with a random person, like on Omegle.com & you don't like the person & you really want them to die you can type in 'i did it for the lulz' three times and 'Smiley' will come up behind them in a short minute and kill them. {NOT REAL. FROM A MOVIE. IF YOU TRY THIS IT WILL NOT WORK.}
