brown expresso 

When you take someone's water bottle that is not see through and take a Shit in it and fill up the remaining space with water. Then put the bottle back were you found it.

This guy is going to have a great surprise when he drinks the brown expresso that i gave him.

Brown Line Express 

1. A fast-moving, no-stops train on the Brown Line.
2. A gigantic turd that tears your sphincter to shreds on the way out. Often comes without warning. So called because of a faint resemblance to a speeding subway car.

Aw man. I had a Brown Line Express this morning. I looked in the toilet, and it was actually the size of my wrist.
