An assloaf.

I dropped a couple of buttmuffins in the toilet just now.

A steaming fresh poop, big and smelly.

I'm baking a hot, fresh buttmuffin for you as we speak

When you blow weed smoke up a lady's vag.

I totally gave Tara a blunt muffin last night.

Buttmuffin

Similar to a "shart"
It is the attempt to fart, but have a solid poop squish in your undies instead.

I was really gassy today but had to run home because I dropped a "buttmuffin"
