Adj. Pertaining to one who is a slut, a cunt, a douche
bag, or a variety of the three. Sluntbag is usually used towards females who cheat on their boyfriends, but can be used on males who give the same courtesy to their girlfriends by
fucking their best
friends.
Devin tried to sleep with
Linda when he's already dating Becky. What a sluntbag move.
Perhaps if
Sarah wasn't such a sluntbag, she would have been better off with her ex Josh.
