To lulz is the act of "lulzing" which is laughing uncontrollably while you are under the influence of alcohol, drugs etc... You may lulz out of random, even when something funny does not happen. Lulzing has no limits! Lulzing also may include crying out of pure laughter, spitting out your drink/having it come out through your nose, ROFL-ing (literally) and most importantly, saying the word "lulz" out loud and/or using it in a sentence while laughing.
While smoking weed, Rory told Carlie she "wants to watch Treehouse, because she is baked out of her mind". While this is not particularly funny, Carlie proceeded to lulz and said "I am lulzing up a storm" through tears of pure joy.

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.

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.

That which you do things for. Theoretically, the lulz can consist of anything that could potentially cause any person or group to burst out in extreme fits of the giggle-snorts. Lulz, being a corruption of the acronym "lol," can also be used as an exclamation of joy gained from a particularly hilarious situation.
