What is Ass Fruit?
The act of taking a shit.
Dude, I just picked the ripest ass fruit.
Ass fruit is basically anal fondue, where-by one person inserts small fruits (grapes, strawberries, etc..) most of, or all of the way into another person's ass and then bites or sucks them out to consume.
I plopped some fruit into my girlfriend's ass, and then enjoyed a nice little buffet of ass fruit as I sucked them out.
