A sex act in which one handcuffs a woman to a treadmill, and rails the s*** out of her.
Also known as "The S.B. Treatment"

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.
