Fuck Buffet 

Fuck buffet: a method of serving up fucking in such a manner as one would have many options for sex but none of them are especially pleasing. In a fuck buffet the emphasis is on quantity of choices as opposed to quality of choices.

Ex- "After joining Tinder, Cindy was able to participate in a veritable fuck buffet of coitus, after which she needed a round of antibiotics."
