A group of 3 bitches or more, unsatisfied with their sexual life, that go out to a restaurant and just wait for the waiter to make the slightest, simplest mistake to devour him alive. The members of the group consist of the bitchy piranha, the bitchiest piranha, and the nice piranha who is willing to let you live.
PS. any attempt to appeal the bitchy piranhas will result in a catastrophic event, so for your safety and the sake of your tips, try to appeal to the nice piranha only.
Damn! i have a group of piranhas on table 21 that is taking most of my time.

A vagina...that is VERY tight. After insertion of penis, into previously mentioned snatch, the penis is overcome with the sensation of being in a very tight place. Thus likening the pussy to a piranha.
Man that girl that I banged last night definitely had a piranha... I don't know if my dick is still attached.

Made famous by Lil' Wayne in Keri Hilson's song "Turnin' Me On"
