The ultimate way to intimidate your opponent. Unlike the wimpish form of this phrase, chewing ass is far more fearsome than beating it.
Fighter 1 - Time to chew some ass and kick some bubble gum, and they are all out of bubble gum!
Fighter 2's inner thoughts - "NOPE NOPE NOPE NOPE NOPEDY NOPE NOPE"
When a person has enough and this is what he says when he wants to kick your ass.
Bully: Alright, problem kid! Bitch!
Me:Shut the fuck up!!!
Bully:You shut the fuck up, you niggard.
Me: Oh yeah?!
Me: *rages
Me: I SHOULD KICK YOUR FUCKING ASS!!!
Me: *kicks the bully to uranus
