1. The ultimate loser, one who has to pay to be sucked off by another loser.

2. A whiny bitch.

3. The one chosen to go and get the beer.

A pick me is a woman that is willing to do anything for male approval. She will embarrass or throw other women under the bus to achieve this goal. The unfortunate thing about a pick me is usually the men they are trying to seek approval from are of poor quality and treat women badly, leaving little real benefit for the pick me.

The ultimate loser; they have to pay to be sucked off by another loser.
A whiny bitch.
