OMGROFLMAO 

OMGROFLMAO: (Expression : Action : Description)
This Acronym, derived from OMG and ROFL simply adds to the expression by adopting MAO, otherwise known as, (My Ass Off.)

In effect, this expresses the writers in the following way.
Oh My God - Rolling On Floor Laughing My Ass Off.

As you can see, this acronym saves a tremendous amount of time typing, and allows others to join in the fun faster than had the writed actually spelled this out.

Andrew (DarkEye): I like boys...
SciTech: OMGROFLMAO
Andrew (DarkEye): Oops, did I type that in the channel?
SciTech: Dumbass...

Ohh My F***ing God I'm Rolling On the Floor Laughing My Ass Off And I Can't Stop It

When something is so hillarious that it's just not enoguh to "LOL" or "ROFL". You really lay down and can't stop laughing (mostly occurs when you're drunk or high on something)

- Did you see that?
- What?

- "OMFGIROFLMAOAICSI"! HHAHAHA
