When you're at a party and you begin to make out with a person, who is not caucasian. (Preferably Asian)

You leave to take a leak, then you come back into the room and start dancing, (thinking that you're dancing with the same Asian,) and continue to make out with her, knowing that you did previously.

However, after sucking face you look over and the girl your buddy is dancing and making out with the same girl, an Asian, and wearing the same shirt as the girl you were making out with.

Then you look at the girl you are making out with and realize that she is not wearing the same shirt, and is not the same girl from the session before you left.

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.
