I really need to know if you can attend this party A-S-A-M-F-P! Hey Johnny, Did you get that M Fin' car started yet? <> For the ultimate effect, add a G D before the M F to abreviate God D*mn Mother F*ckin for ultimate stress relief without offending. EX Hello, I'd like you to meet my G D to the M F boss Mr. Sucabut.

Word for the girl you sleep with and refuse to call her, unless its for more sex. Also a way for friends to notify other friends when the booty call is in the vicinity.

Guy 1: Dude did you see M.F.?
Guy 2: Yeah! She walked by your job, and was looking for you.

Guy 1: Ok, shout out M.F. if she returns.

aka mold farm. A perfect place to hide rotten ravioli and popcorn kernels as well as any other random shit you may encounter in your fridge. this may include milk, pancakes, vinegar, bread, eggs, and CLAUSSEN pickles. beware of maggots and older, slightly more mature people finding it in a cabinet in your basement.

The kids parents were f-ing pissed when they found that bad-ass m.f. in the cellar because it smelled like corn chunkidge.
