Poor college student who regularly exchanges sexual favors for the chance to be treated to dinner; not necessarily a common slut, only when it counts. Tactics often include the hungerslut inviting the victim over and asking if they are hungry. Hungersluts are not hard to please and often suggest the cheapest food in order to avoid suspicion.
-I'm gonna invite him over. He might buy me pizza.
-You are such a hungerslut.
