Muffin Butting

Muffin Butting is the act of inserting a muffin into ones rectum before expelling it through a bowel movement.

I spent yesterday Muffin Butting and have been clearing crumbs out of my ass for hours.

Thumb-butting

When you are hitting it from behind and have your thumb in her butt at the same time. Thumb-butting it.

She seemed like she wanted it so to test the waters I was thumb-butting it.
