Hey look at pony tail dude. Yeah, what a Hair Compensator...he went bald on top so he is making up for it by growing it long in the back. At least it's better than a comb-over Trump style !

over compensator 

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.

Compensated Dating 

Translated from the Japanese word, 「援助交際 」or "Enjo-kōsai." Compensated Dating is a term used to describe young women going on dates with older men in exchange for money or gifts. These dates often end in sexual activities. It is a form of prostitution, however most women who participate in Enjo-kōsai do not view themselves as prostitutes.

Although this term originated in Japan, compensated dating has spread to other East Asian countries and has even stretched to the USA under the phrases sugar daddy and sugar baby.

See enjo kosai.

Friend A: You're doing compensated dating? Isn't that really horrible and shady?!

Friend B: What does it matter? These older men are giving me a shit ton of money.
