Someone who spends the colder months with their body pressed against various radiators. A radiator whore does not discriminate: if it's warm, they'll be stuck on it.
Guy1: God, look at that girl rubbing up against the radiator. She's such a radiator whore.

Guy2: Yeah, and she was just all over the heater next door too...What a slut.
