An ass muffin is, when you take a dirty sock and shove it up somones ass. Then you rip it out of their ass, and eat whatever is on the sock. Then you wrap a condom around their head, and fuck them in the mouth.

The smell that exists when a bunch of teenage boys sleep and eat in the same room for over 24 hours without showering. If you experience the ass muffin smell you are advised to internally combust, because your life is over.

The act of stuffing one or many muffins down your pants, while promptly sitting down on the doughy mass. Upon sitting, you take the muffin mass, ball it up and eat it.
