Nutritional yeast, a cornerstone of the vegan diet.

When you think up something brilliantly righteous while baked.

Nutritional yeast, the pungent yellow vitamin B-12-filled flakes loved by vegans everywhere. It tastes delicious in cheezy sauces and many other dishes. The term "nooch" was coined by the PPK.

An expression used at the end of a joke or a bashing.

A blank word having no meaning except the one you want it to

A distinct facial expression featuring a very exaggerated frown in which the corners of the mouth are drawn down, almost to the jawline. The lower the corners, the better the nooch. Not unlike the face of a very grumpy, disgruntled, old man.

Just kidding, don't kick my ass. (Usually at the end of a sentence containing an insult.)
