A woman who has beaten every turn and who can not catch a break in life. Usually a used up crack head, or corner prostitute, though can also be explained as a fat assed white trash lady that lives in the busted down house in the middle of your block who has more used car parts in her lawn then grass.
Bob: "What seems to be the problem here, miss?"
Ugly ho on the side of the road: "Looks like my car's broke down, can you help me out?"
Bob: "That's not the only thingthat's broke down. Later, skank."
