A term that defines a person who has dated an unimaginable amount of people, usually all in the same social group. The term is used because of the similarity between the feelings towards drinking your friend's backwash and dating your friend's ex.
Also known as the second-hand spouse.
"So on Friday I'm going on a date with Evan."
"Girl, I wouldn't even TOUCH that guy. He's a major case of backwash."
