I did it for the lulz
Beginning as a plural variant of lol, Lulz was originally an exclamation but is now often used as a noun meaning interesting or funny internet content.
Lol -> lul; lols -> luls; lolz -> lulz.
Lulz is the one good reason to do anything, from trolling to rape. After every action taken, you must make the epilogic dubious disclaimer: "I did it for the lulz".
This has been pioneered by encyclopedia dramatica, famous for posting a fake craigslist add and then listing the personal info of those who responded.
"Why did he post a suicide note on livejournal before killing himself?" "I hear he did it for the lulz."
Lulz.. is a corruption of L.O.L., which stands for laugh out loud.
1. Anonymous gets BIG lulz from pulling random pranks!
2. ..But truely EPIC lulz come from raids and invasions.
on steroids will do anything to get epic lulz."
Lulz is a typographical subversion of the word "lol", meaning to Laugh Out Loud, thus emphasising the humour derived from the subject by way of making the original word sillier.
Citizens of Hiroshima and Nagasaki: "Why Truman? Why the bomb? It killed thousands of innocent women and children"
President Harry Truman: "I did it for the lulz"
Phil Shuman used this term in a poorly executed last minute piece that was thrown together. It shows his complete lack of ability to perform proper investigative reporting. Many LULZ were generated from this attempt.

1. A corruption of 'lol' or a purpose misspelling of 'lol'.
2. An idiotic excuse to do ANYTHING offensive or disturbing (and as such, funny) used mostly by Chantards (4chan, IIchan, etc.) Gaiafags, or any usual member of Encyclopedia Dramatica.
3. Something funny that is caused at the expensive of others.
