Whenever I hear something like this my first thought is that it's some stupid TikTok "challenge" that's intended to get people to humiliate/injure themselves on camera for the lols.
There was a show called “my weird addiction” or something similar. A young good looking couple would frequently take breaks to do coffee enemas. She likes “Java” or something, he preferred something else and more like espresso. I think they had a kid. Only episode I ever watched.
