1). A dumpster for cum, such as any repository in which cum might be deposited, stored, and maintained; 2). A really ugly person having no redeeming value except for other people to use for sex, aka dump their cum.

Get the Cum dumpstermug. 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

Get the cum dumpstermug. Referenced as a sperm repository or a good name to call people while tossing salads at Sheetz. This word is commonly used with the word "Overweight." This is the word that has the most complaints against workers, usually workers namesd Caleb at sheetz.
