Brown Line

The railway that runs alongside the Hershey Highway.

Ooop, I feel a Brown Line Express coming through...

brown line

The stain left after a wedgie occurs in undershorts. A brown line results if wiping is not sufficient after a bowel movement or a sudden burst of gas is released unexpectedly.

I hope your mom uses Tide to scrub your brown lines out of your underwear.

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.

The Brown Line

How close you can come to shitting yourself, without actually shitting yourself. Usually caused by explosive diarrhea.

I almost crossed the brown line this morning, I Just managed to get my pants down and take a seat before I decorated the Oval Office
