chasing that feeling is drinking white wine, smoking Shake, sniffing amyl, and masturbating trying to reach the point-of-no-return which is just about but not quite before you have an awesome cumgasm.
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!
