Goblin Town 

The area between the rectum and the surface walls around it when pushing out.

I stuck my finger up my own anus and I could just ring around goblin town with my finger

Down Down to Goblin Town 

A song from the 1977 movie The Hobbit inspired by J.R.R.Tolkien.

References a place in the realm of Middle Earth.

Which plays during the movie when the Dwarves and Bilbo Baggins are ambushed and captured by Goblins.

South Park parodied the 1977 song during their Wikileaks episode, when Lemmiwinks is stopping Wikileaks.

"Down Down to Goblin Town."
"Down Down to Goblin Town."
Usually anything related to goblins or Lord of the Rings will end in singing this song.
