Windmill style is the name given to a unusal style of street fighting.
It is unique and not very pretty to watch. If it is performed correctly by a person who has the right attitude, lets say a demented psycho. It can be extremely effective.
But hey if nothing else, It sound like you mean business at least.
"If you don't shut your fucken squeal hole real soon, I'm gunna come over there and fucken fly you windmill style, ya cunt!"
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!
