I heard it again - Uncscious, or perhaps as LL pointed out Unctuous. I heard it on The Food Network on Guy’s Big Bite – Backyard. He was frying bacon and refered to it as “unctuously fatty” or something to that effect.
I think unctuous, meaning fatty, oily, greasy is similar to my uncscious although I added delicious, succulent, luscious, rich, decadent to the definition.
I’m going to keep listening to see if I hear it more and more, just as long as no one calls me uncsciously (or unctuously) fatty any time soon I’m good.
