Jatter is the word combination of jab and chatter. It is usually the insulting words you hear when separating two people from fighting and they continue to berate each other. It can also mean when one backs down from fighting and the other continues to incite them by yelling back insults in a clear attempt to goad them into fighting. The third is when one wants to fight the other and does so to entice them with rude insulting words.
"Okay okay, break it up ! We're not going to have a fight in my establishment."
"That's fine with me, I really don't want to fight him."
"Yeah, you would say that you yellow-belly punk-ass teat-sucking momma's boy !"
"Dude, just ignore his Jatter. Walk away. He's only trying to get at you."
Often influenced by long nights and after parties.
