the game played when one does not know the rumblings of the colon ismass or gas. one can choose mass, and tighten the sphincter and wait to go to a safe location or one can choose gas and releasing the floodgates, thus either farting or shitting their pants. months of ridicule may ensue as well as violence if done on a road trip
I was on my way to phoenix and the rest stop was closed so i decided to play mass or gas. i lost and shit my pants.
