when someone is the persons bitch & are all about them. it's almost like there the persons third nut or 2nd vagina. (pipe is another meaning for dick) & since your on the persons dick a.k.a pipe (on a persons dick also means being the persons bitch/obsessed with them) you mind as well ride it! since riding pipe doesnt sound right its switched around to pipe rider. (pipe rider sounds much better then dick rider) its catchy to say right?

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.
