Laughing out loud with style!
Normally its used so u don't sound
boring saying "lol" every 5 seconds.
The "z" doesn't mean anything really
its more of spongebob's and patricks
Z is for flare baby! ;3
It also can be used for an awkward laugh
in strange "wtf" situations.
Kid: dude what's up?
Kid2: Nothing man, i just broke my neck
on a skateboard while trying to slap
Kid: wtf? lolz....
