They're just referring to normal habits we all do like checking your oven for the family of mice you let live there before leaving for work or brushing your teeth one tooth at a time while watching the Flintstones in a language you don't understand. We all do it.

Gotta make sure everything is locked, helps with pooping.

While I don't fully disrobe, the freedom of pulling one leg out of my pants is amazing. You can get a nice spread going for those times you need to bear down a bit.

I don't know about every time, but I've had an intestinal blockage. Everything came off. I was sweating and crying for what felt like hours. Pooping was the best feeling I've ever had at that moment.

It's a habit like licking the bottom of your shoes when you get home.
