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?
Yeah.
Oh yeah, she's definatly been bone thrown.
Getting plowed so hard you get thrown across the room.
I can tell Caitlin was bone-thrown last night by her odd gait.
