The beer shits you get after a long night of drinking the greatest beer on the market, Rolling Rock premium beer. Much like the bottle, it has a definitive green color to it, and, like the beer shits you get from drinking bud light, it comes in waves of 2 to 3, maybe 4 trips to the bathroom. However, Rolling Runs has minimal/no odor, and that's a plus.
I drank too much Rolling Rock last night at that party, now I have the rolling runs.
