A sexual position whereas a male goat's ass is placed over a man who is wearing seran wrap across his face. The goat takes a shit over the man's mouth, onto the seran wrap, depressing the seran wrap into the man's mouth. Meanwhile, the man brings the goat to orgasm via a reach around. Thus, the shit is "just in", and the goat "nutts".

Kind of a combination of the man getting a Hot Carl, while the goat gets a blumpkin. More often seen in Kansas.
I was going to the barn to feed my pet goat Fluffy, but when I got there my friend from Kansas was giving Fluffy a Just-in-Nutt.
