Manslap - when a grown man whines, bitches and moans to a point where you as a man would need to open-hand slap another man. A necessary gesture and action to quickly check a man and put him in his place, undeserving of a typical punch.
I went out with Brad the other night and he was just being annoying...Whining and complaining about nothing so I had to manslap him and check him real quick. He deserved it.
