bumcum

A translucent, beige, sticky, mucus created in the rectum by the body to help prevent log jams.

...so i ended up at her house and she opened a drawer full of toys but I had to pick the dried bumcum off her butt plug before we could use it...

I thought there was a monster turd brewing but I sat there for 15 minutes and only managed to fart out a teaspoon of bumcum.
