the underground railroad

The toilet and/or the entire human fecal system.

Called the underground railroad because "black shit escapes."

Goddamnit, I better go visit the underground railroad.

Elevated underground railroad

The part of the subway that runs above ground.

The black people were in plain sight of the racists while on the elevated underground railroad portion of the underground railroad.

Underground Food Railroad

n. the secret pathway that you put your extra food on when you're at somebody's house that does not like to waste food. In the Underground Food Railroad, you must work as a team to get rid of the extra food. This is usually used when there is a buffet and you accidentally get too much food.

I got too much food at the buffet... Granddad will be mad...I think I'm gonna use the Underground Food Railroad...
