When the toilet is clogged and you plunge it down using your foot.
The origin of Shitfoot is when Aria Nafeces brought his shit stained shoe into class and smeared satanic rituals/ naruto jutsus all over the
floor. He was soon taken out of the class to wash his shoe in the bathroom, which took copious amounts of times, and the poor
chair was taken to maintenance.
Since the fateful shitfoot
day of September 4th
2018, it is said that if you plunge your shit clogged toilet three times and
say "Shitfoot No Jutsu", you will summon Shitfoot himself to your bathroom. He will then smear shit all over you.
"Have you heard of that Aditya
kid? He's
pretty stinky. He must have shitfoot."
"Yeah man, that shit stinks like clogged toilets, shitfoot
indeed."
