A "Nut Brownie" is the act of anal sex. Very fast anal sex. Why fast? Because if you fuck a chick in the ass very fast and pull out quickly she will shit all over your nuts.
Thus creating a Nut Brownie.
What else is there to say?
Go ahead, try it out.

If you dare.

Example should include the word "Nut Brownie"

So Nut Brownie. Nukka.
