I went to the club last night and had an opportunkitty to smash this Ho, but she was so sloppy I decided to bounce and go home with a carne asada burrito instead.
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!
