Rolling On Floor Laughing My Mother Fucking Ass Off All The Way To God Damn Canada. To use when you're in the mood to sound like a total imbecile while confusing all of humanity at the very same time. Woohoo! You can now make even more of a fool out of yourself! For BEST confusing effect, don't define the confusing chain of letters for your totally clueless friends/acquaintances/enemies/lonely mimes.

Oh my god! That was SOOO friggin' funny! ROFLMMFAOATWTGDC!!!!! Ah-hah-hahaha!!
