Buttlitter

Any form of defecation that occurs outside of an approved excrement release site such as a toilet.

After the long trip back home, I couldn't make it to a bathroom, so I had to make a stop to drop some buttlitter in the woods.

buttwiper

Derogatory term referring to the domestic beer Budweiser. The term is fitting since, after drinking many Budweisers, the very next thing you will be doing is wiping your butt, and frequently.

That last buttwiper didn't go down so well. I think I'd better hit the toilet and fast!
