The high increase in popularity of the infamous LOL (laughing out loud) was not enough for the teenage, trying to be cool, defying mom and dad, often emo generation. They had to come up with something even cooler and that's how LOLZ was born. Some say that Z stands for S, therefore it's the plural version of LOL. But let's analyze that thought process a bit. The plural of LOL would be translated as "laughing out loudS" or "laughingS out loud" which, for the few of us who are at least trying to be grammatically correct makes as much sense as "z" being used as a replacement for "s".
In this case, the Z could be interpreted as the initial of a completely different word. Possibilities:

1. Laughing out loud ZBANG! - this would indicate that the violent laughter has caused the person to fall and hit the ground, thus creating a loud sound;
2. Laughing out loud ZTUPID - seeing as Z is so often used as a replacement for S, it makes sense. It's also a very positive thing, when you consider that admitting you have a problem is the first step to recovery;
3. Laughing out loud ZENITH - the person doing the laughing has entered a state of astral trance...
A: - I'm a complete idiot, with absolutely 0 knowledge about anything even remotely intelligent
B: - Lolz

Still having the same definition as the traditional lol, it is simply another version to break the monotony of such an overused phrase.

1. 'Laugh out loud lots'. lol + lots => lolz.
2. I want you to think that was really funny when actually i can't be bothered to type anything else.

LAUGH OUT LOUD ZILLIONS

Laughing out loud zillions of times like a moron. Skinny, tall, white males in their early twenties do this. They tend to post "LOLZ" on other people's Facebook walls while interrupting a conversation between other people and pretend they patented the phrase. Really, the term "LOLZ" is just another way of saying they are lacking down below. LOLZ
Fred: I saw a funny commercial the other day, it made me laugh.
Juan: Was that the one with the big dog?
Fred: Yea, that was it!
Andrew: LOLZ! Hey guys, can I be included in this conversation?

When someone laughs out loud, then instantly falls asleep, usually a narcoleptic. If they choose to fall aslep, it written lolzzzzzzzzzzzzzzzzzz.

The instant desire to fall asleep after something humourus has occured.
Wow, that was so funny, it made me drowsy, lolzzzzzzzz.

A Word used to often replace "Haha" or "LOL" or "XD".
It is usually said in response to something that isn't even very funny, and therefore it is said typically in a sarcastic tone.
Ya its was hilarious...Lolz
