Basically what has been done to a slut or girl who absorbs a lot of penis into various orifices.
Man that sorority girl has totally been BONE THROWN.
Repeatedly railed/sexed/banged or otherwise "boned" by many people.
Holy Shit! I can't remember a thing about last night, I didn't hook up with that one chick did I?
The one you met on highway 99?
