Men who use this term are admitting that their own dicks ruin women, creating a great argument for why women should never sleep with them. If you think women are "ran-through" for sleeping with lots of men, then the only conclusion one can draw is that women should stop sleeping with men--including YOU.

It is a sexist, self-owning term that only exists because of men who are too insecure about their own lack of sexual success that they feel the need to insult women--women who are living the life they so desperately wish they had, by the way.

"Ran-through" comes from jealousy, first and foremost.
