FYMP 

Abbreviation for FUCK YOUR MOTHER, PUNK
Extreme put down- completely disrespectful

Someone asked what the FYMP meant that I have tattooed on my wrist. I replied,

"FUCK YOUR MOTHER, PUNK."

fympho

A woman who pretends to be a nympho (a woman addicted to sex.) This woman is usually a virgin but pretends that she's a nympho to get attention from the opposite sex.

I have two friends whose name's are nympho and fympho. One is a slut and the other just pretends to be (which is just as bad)

A girl who thinks she's a nymph, but she really is not.

Whoa, that girl said she's a nymph, but she's actually a fymph.
