The wetback shit is the act of taking a shit and sneezing. The
sneeze propels your shit out of your the anus at a higher than
average rate. As the shit licks the surface of the water, it causes a large ammount of water to discharge from inside the
bowl into your anus thus resulting in a wetback shit.
Man 1: Last night i was looking to take a peaceful shit. I brought my magazine in with me as usual. Suddenly I had an urge to
sneeze. I had been prairie dogging it for a
good four hours previous to this. As i sneezed, the shit propelled out of my anus and i received The Wetback Shit.
Man 2:
Gross.
