A word used to describe very easy young ladies chasing men around nightclubs and bars for either drinks, sex or money. Relationship is not a part of their vocabulary, so do not be fooled into believing it is what they want. Slag: because they do not care who they are after. Hound: They will be climbing on top of you before you know it (Much like a dog trying to hump someone's leg!)
Mate, let's not go in there tonight... it's full of Slag Hounds, they'll be all over us.
