A form of group sex involving 3 or more people,at least one being a male. You take a pineapple and cut the top off, and then carve hole in the fruit about the size of your penis. Then, shove the pineapple up the takers asshole and put your penis in the hole in the pineapple. The third person sits under them and licks the anal citrus blood blend that drips out of the takers asshole.
Dude, your mom was pineappleing with two guys the other day.
