1 definition by One Unintended

An individual (typically female) who unwittingly enters into a part-time relationship during the coldest season of the year, as drinking establishments close early and opportunities for casual sex become less available yet prohibitively more expensive, merely to satisfy someone's needs.
Distinctive pattern of a winter warmer:

- (Autumn equinox)
- Boy snares girl
- Boy invites girl to residence for sex
- (moment of climax)
- Boy turns on Sports News channel
- Girl gets bored and goes home
- Boy smiles
- (Spring equinox)
- Boy ends relationship, goes nightclubbing
