some one/thing that follow you but you dont want it to be

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.

Someone who is worthless and has no friends. A nobody. Someone who is inferior to a piss stain on a public highway rest top urinal.

Someone who is really annoying and you really can't stand.
