PMFAO

When Bill Hopp JR. thinks something is hilarious, the term PMFAO will be given in place of "LMFAO"
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"

pmfag 

a pmfag is a dude who acts completely normal during the day but at night becomes a complete fag and lives a second life dedicated to butt sex with men.

Larry is such a pmfag. I caught him riding in the car with that queer dnatello last night and he tried to say oh my car broke down but they were riding in his car at the time... dumb ass faggot.
