Jive turkey wasn't really fighting words though. Depending on the situation, it is like calling somebody a fuckboy or saying, "You ain't shit" for some minor infraction.
I can remember when calling a muhfucka a "motherfucker" actually implied incest and was an insult that WOULD bring people to blows.
I can also remember being ready to fight over being called "dawg" when I first moved to Milwaukee in 1980.
