look up any word, like the eiffel tower:
The act of doing something that makes you laugh or amuses you.
"Why the hell did you break my camera?!"
"I did it for teh lulz!"

The only reason anyone does anything
Person 1: Why did you did it?
Person 2: I did it for teh lulz.

For the laughs or for the entertainment.
