If you mean the “I need to go 3 days pooping as much as possible” post, it’s a reference to this post from a couple days ago

Oh god not silverfish, I had a few in my bathroom a while back and I spent like three weeks spraying all the nooks and crannies with lavender-scented spray every day to make sure no more of them came back. I like bugs but those are some creepy little fuckers. And they eat your books!
