YDNNM is an acronym for the phrase "You don't need no man". This saying is most commonly used by individuals who foster feminist ideals, as it suggests that one does not need another of the opposite gender in order to survive. It is an acronym used to bolster one's self confidence after a breakup, or just to remind a friend that they are a wonderful individual who is not in need of a companion for completion.
"Bitch please. You have a sexy bod, a hot car, YDNNM!"
