Ice Cube the rapper.
Not really a gangsta; he's a rapper/actor, but he is good.
Formerly of NWA before all that shit happened, now an even better soloist.
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!
