A person who flirts with one or more of the people in charge of a party, in order to get preffered treatment at the keg. The more brazen keg whores will even try to get a "house cup" (free beer).

Keg whores are considered to be the worst kind of a cock tease. Be wary of anyone flirting with you while you're running the keg.
Amy seemed interested in my last night, but Zack told me she's just a keg whore.
