(verb) An actor is k-paxed if he stinks so badly in a film (such as Kevin Spacey in K-PAX), that it makes you realize you dislike every previous role of his. In typical cases, all other movies he/she has been in are now ruined for you, even ones you previously didn't mind.
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!
