There used to be such a thing as “fighting words” and “fighting gestures” that would legally justify hitting someone that cursed you, or flipped you off, insulted your family.

Still exists, but is now an exclusive right of black thugs.
That's why the word "dissin'" exists.

Does not apply to the knockout "game" however.

Good point. I guess we are supposed to wait until they knock us out, we wake up and then try and find the nasty skank and fight back. Na uh, no more. It pays to be on alert.
