This girl told me not to BS her about meeting her at a club, then she goes and Tweets about how she's with some other dude at a club down the street from the one I was at... how rudical is 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!
