It was more the lack of an explanation that hooked people, rather than just the not pooping - IIRC, we never ended up getting any real explanation for why this guy needed to not poop for a week.

It was honestly pretty great, people came up with everything from "he's smuggling himself internationally in a shipping container" to "he's determined to be the winner in a really weird Mr Beast video" to "he's giving up on society to live with the sloths" before it started to turn into kind of a circle-jerk.

And of course, suggestions for stopping the poop included butt plugs, eating only cheese, butt plugs, a liquid diet, and more butt plugs.
