a swexually abused person aka Subspace in the sexual bondage lifestyle. Get's cummed on and/or in without being thought of, not cared for, literally like a urinal for piss....used and spiritually abused.
"Lay on your stomach..." he flips him/her over so that there is no ee contact and he humps until he ejaculates almost as though he were masturbating (alone) just him and that hole he just "dumped his cum into" hence: Cum Dumpster
