The term "buttmuffin" is an affectionate term, a term of endearment, used to describe a person with a nice ass (usually a female) โ€“ the "butt" referring to ass, of course, and the "muffin" being a reference to a soft, sweet, sponge cake.

The term "buttmuffin" may also be used to describe a person with a particular fondness for nice, or "sweet", asses; however, the term is not descriptive of faeces, in any way.

I tried to take a shit yesterday and I couldn't get the turd out, there was a little inside of my anus for like five min; man that buttmuffin was a tough one!
