Slao, also known as Slaoing. Is the term used when a male sticks their genitalia into an airvent (be it large or small, preference is yours) and then turns the air on.
"Man, you should have seen Jared the other night. He was trying to get everyone to Slao it up."
"I dunno, I could go for some Slaoing right now."
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!
