Someone who lives in a run-down neighborhood, but has expensive possessions. Or if someone in the hood has multiple cars or if there is a known drug dealer who has a nice house in the projects, you might say he is Ghetto Fancy.
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!
