When eating at a teppanyaki restaurant, one places his or her hand on the teppanyaki grill. The longer one holds their hand on the grill, the better the handshake.
Wow man! I can't believe you did a 10 second teppanyaki handshake! How's your hand feeling after that!?
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!
