A man who tries way too hard to feel better about having a small penis. Usually seen trying to impress women with cars, cash, clothes, or a macho attitude. This showing off helps them to think that people dont know about the small johnson. Most often, over compensators have no actual personality or character. Usually loners that hide the fact that they really want to kill themselves because of their tiny penises.
Tom Brady is a totally perfect example of an over compensator.
