The act of sexual intercourse in the doggy style position in which you insert your thumb into the anus in a twisting motion, causing the recipient to "nay" like a horse.

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.
