The few words, if any, to say before a fight ensues.
The most common topics to insult are:
Your Mom/dad Your sister/brother Your close friend
Your girlfriend/boyfriend
Your wife/husband
Your son/daughter
Your pet
Your financial situation
Or anything else you take seriously
(Both Max, the innocent bystander & Rick are standing in a alleyway, about to fight.)
Max: Any last words? (He punches his knuckles together and then gets into a fighting stance.)
Rick: I'm gonna kick your fucking ass! (He glides his arms around him to end up with him getting into a fighting stance, both said their fighting words.)
An insult or insults that are sufficiently offensive to the insulted person that he/she becomes angry enough to start throwing punches.
Person 1: Too bad your mama didn't drown you when you were born, you worthless nigger/kike/camel jockey/bitch/cracker/gook/insert chosen offensive word(s) here!
Person 2: I'm gonna beat your ass! Them's fightin' words!
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
