A person, most commonly a young female, who flirts with members of the opposite sex (or sometimes same sex, see homosexual) in order to obtain said person's sweater. The sweater may be used for warmth or tied around the waist as a show of power.
Ahh man, its so cold!

That sweater whore from school 'borrowed' it again. How can i say no to a rack that big?!?
