What is the definition of leet

This is gamer terminology. This is a form of the English language shortened for mainly gamers for shortening the length of time spent typing. Or sometimes, for fun or it sounds weird/cool.

ex:
lol = laugh out loud
rofl = roll on floor laughing
rotfl = roll on the floor laughing
lmao = laugh my ass off
wth = what the hell
wtf = what the f*** (sorry, this is obscene, but I believe it helps)
