The act of a boss or manager scheduling you for certain shifts so that you avoid working along side someone you are trying to have sex with. Cock blocking you by giving you bad shifts.
Man, there's this new girl at work who is so hot! But I never work with her, my manager is always shift blocking me.
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!
