A fart trapped between two turds; desperate to escape, the fart propels the first turd with intense velocity. Often gives the feeling of having the runs, however in most situations this is not the case.
I was dying on a dump this morning, 100% touching cloth, I thought I had the shits - but as it happens it was just a fart sandwich.
