Funderburg

When a female is having a hard time pooping so she inserts her thumb into her vagina to help push out that last bit of turd.

Holy shit Aubrey! I was so constipated this morning even the coffee wasn’t working. I had no choice but to give myself the old thumbs up and Funderburg that crap right out of there!
