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!"
