An acronym for the phrase " Fart on you later in your sleep"
This phrase is loosely used when personally referring to someone specifically, especially when other motives are involved. Usually it is part of a sexual act, compared to animal mating calls, Foyliys is thought to be the same kind of implication. This phrase can be playful, or serious.
Guy: hey babe I got to go, See you later?
Girl: Yes Foyliys
Guy: oh.... damnnn.. I'll get the nose plugs ;)
