when you go to a friend's house, go to their backyard, take a huge dump on the ground, preferably under a deck... then cover it with bird seed to give it a good look
Big Jon came to my house the other day just to give me a bird seed splatter.
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!
