PMFAO: Popping My Fucking Ass Off.

Bill likes popcorn so much, he has to "Pop" his ass off.

Bill Hopp JR. looks at a GFS Snow map in the middle of January. It shows a 3 foot blizzard for Baltimore.

"PMFAO he says! It's going to happen because JB mentioned it earlier"

PMAO

Contraction between "Pissing me off" and LMAO. It means that you are extremely pissed on someone or something.

Your Boss: "Hey would you please file all these documents to the archives?'
To yourself: Huh... PMAO!

PMAO

A mixture of lmao (laughing my arse off) and pmsl (pissing myself)

Dotty laughing with her friend finished with "pmao" in error instead of lmao or pmsl and the new hybrid word was born!!
