Someone who has just been patched in a motorcycle club and thinks they run the world. They have no reguards to anything else except that they have been patch and they are highly obsessed with themselves. Nothing willstop them.
Dude, have you seen Chris lately? Ever since he got patched, he's such a patchhead.
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!
