Someone that doesn't have sexual attraction to people on a day to day basis, and doesn't want to have sex with almost anyone, but would make exceptions on rare occasions if given the option to have sex with very rare people

A hardo is a person who tries extremely hard at everything. Most times a hardo will try very hard at things that do not require excessive effort. For example, sports practices, gym class, etc.
Wow did you see Jack at practice today? What a hardo!
