zomgroflmfaocopterskaterz! 

A leet speak exclamation. Direct translation from 1337sp34k to English: Z-Oh My God, Roll on Floor Laughing my Fat Ass Off, Copter (as in roflcopter,) skaterz (as in lollerskates.) It is quite the exclamation

Me: So I totally boned Veronica "Tits McGee" last night.
David: zomgroflmfaocopterskaterz!.
Me: That pretty much sums up the experience.

zomfgroflmfao 

A combination of zomfg and roflmfao. The z originated from accidentally pressing z instead of shift. After that, it stands for "Oh my fucking God rolling on floor laughing my fucking ass off"
This word was invented by me, The Scyphozoa of CoD, and ggganz of civfanatics. I have never seen anyone but me use it.
Usually spelled in all caps. Rarely would you use z0mfgr0flm40 (it's 1337 equivalent).
