The result of a person (or organisation) disappearing so far up their own backside that they warp a hole in spacetime from which not evenlogic can escape.
I came perilously close to the event horizon of a brownhole today and frankly, I'm lucky not to be buried in a whole heap of super-dense shit.
A particularly strewn-out bowel movement in which the end result can resemble a long wriggling worm. It can also form what appears to be a "Mr whippy" in the bowl.

Brownwood is a mess. Most residents have been doing drugs since the age of 11. Many come from an inbred family. They dress like they are uncivilized. Their favorite food is donuts, and they like going to the park. They drink a lot and go to jail often. They are also homophobic and racist. Overall Brownwood is a terrible place to live.
A town in Texas that has become known for its tolerance towards the homosexual lifestyle. In honor of Brownwood's acceptance of alternative lifestyle, the term Brownwood has been associated with gay anal intercourse.
