one hit bro
A colloquial phrase often loudly professed by sub-humanoid residents of the New Jersey shore, often in self-admiration of one's ability to render another Jerseyan unconscious in a single hit.
Yeah bro, this one bro was like "hey bro i dont like the way you fist pump bro" so i fuckin' knocked him on his ass in one hit and was like "one hit bro!"
