Might be, but it's also very much doable.

When I went to confirmation camp, it was on an island with no water toilets, only outhouses. Some of my peers just wouldn't use them for shitting, as they had never had to be without a "regular" toilet.

When there was a visiting day like a week after the start of the camp, I think someone had felt too nauseous and given in. I know this because I was assigned to empty the outhouse barrels. Which some mischievous visitors (older siblings who had gone through the camp themselves a year or couple before) had filled up to the brim with a hose, so all the shit was in liquid.

When we emptied them I saw a shit log the size of my forearm. All veiny and shit. Wouldn't be out of place in the South Park episode about massive poos.

So idk man, I think it's a joke but also, people do do that. ("Doo-doo", hehehe.)

You sweet summer child
