In the oil rich province of Alberta, Canada, this is a sexual position, where the man is standing over the woman, who is in the roasted chicken position, with his back to her he then crouches down and pushes his hard-on (vertically) straight down into her snatch.
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!
