 I guess U-N-T-A probably. It can be a noun or a verb, or it refers to that piece of bread that you use to sop up the last good bite of whatever it is you're eating. So if you see something, there's still sauce left on the plate or something in a stew, you're like, oh, that would be good uncha. Or if you see something that you're going to do that to, you would grab your piece of bread and say, I'm going to uncha, and then sop it up.
