Lame attempts at being cool

Lolz, Haihz, Hahahz, Lolx... Ok you get my point! (if you dont, you're just plain dumb)
Why... do some people add these annoying letters behind those acronyms or wateva and think it's cool?
No! Adding irrelevant shit like that does not make you suddenly the envy of all people. Jeez!
LoL = Laugh out Loud (D'uhh!)
but when you add the "Z"... What does it make it? Laugh out Loud Zebra? Zit?
For some very odd reason, people seem to think that the letters "Z" and "X" makes one sound soooo cool!

E.g = xX Loco Dude Xx or X-tazy

Sigh... you know what? Just go on doing what you're doing. You "cool dudeZ" are a very good source of entertainment for us.
