This is where you and a friend or even someone you don't know are taking a dump in a line of stalls. You then roll up little peices of toilet paper and roll them underneath that person's stall as if it's tumbleweed.
"So I was taking a dump the other day and this kid kept rolling toilet paper balls through my stall and it looked like tumbleweed! It was great!!!"
