An annoying jerkweed who when asked for his menu choice replies "the usual", despite no one having any idea or really caring what this candy-ass wants.
"Hey, Phillippe! We got a usualer at table 6. What does he get?"
"Who knows, man! Wait, what's that on the ground? Here, put it with some meatloaf....no, no, pimp it up, man! Yeah, like that...go give that to the usualer...now that's the shiznit!"
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!
