What is Brown Tail?
1.
The little string of poo that is half in your butt and half out after going #2. Usually caused by premature clinching of the ass muscles before everything is completely evacuated. It resembles as small brown tail, especially when you "wag" it trying to get it to fall off. Leads to
Hal: "Dude, I took a massive dump about 2 feet long, but was left with a brown tail."
Rump: "What did you do?"
Hal: "I jiggled around for about 5 minutes with no luck and eventually went through a whole roll of toilet paper cleaning it up."
