lolzzz 

A sub-form of lol. The scheme of how lolzzz was born is:
lol (laugh out loud) -> lols (plural form of a loud laugh) -> lolz (cooler way of the same) -> lolzz (supposedly even more cooler) -> lolzzz.
Lolzzz is usually written, not spoken, but a common pronouncement is 'lol' + a long 'z' getting lower and quieter (like a landing jet plane). It can also be pronounced 'lol-z' with a very abrupt Z.
Lolzzz can refer both to something very funny or something not really funny.

A: My boss recently bought a new PC and bragged about it all day until it showed a BSOD and wouldn't restart anymore.
B: Lolzzz!

A: My neighbour's cat yesterday saw a speeding truck and got scared half to death, ran up a tree and didn't come down until the next morning, isn't it funny?
B: Lolzzz. Poor kitty.

Lolzzzz 

Internet slang, used when you think something intended to be funny is not. The "zzzz" represents falling asleep. This word looks similar to "lolz", meaning multiple laughs. However, the definitions are opposite.

This word could be used with as many "Z"s as necessary, depending how lame the joke/story is.

Girl: Hey, why did the chicken cross the road? To get to the other side! Hahaha!

Boy: Lolzzzzzz
