Country Dictionary

Not to be confused with dumbass, DUMB-ASS actually refers to any stupider-than-stupid female in a TV show or movie that is such a mong, they're only good for their ass (to have sex with, given most DUMB-ASSes have fairly good looks). Note that in order for a female to be classified as a DUMB-ASS, they generally have to do something stupid and blatantly obvious that ends up killing themselves.
