A skank, butt slut, whore, etc. that is usually black (not a requirement) and not at all intelligent (a definite requirement). This word is preferable as it is not considered foul language when used yet seems to get the point across to the opposite party much more effectively. This word is not yet widely used, so many do not know its meaning when it is used. So feel free to elaborate when using the word. Hoofies usually need multiple explanations anyways as they are not the sharpest tools in the shed.
