Do you ever use the toilet as a backrest?

I wouldn't do this in a public restroom, but in my own home where I'm sure - confident &/or convinced at least - that it's nobody's urine but my own on the backsplash, I'll for sure lean back and relax while I'm deucing/boarding. Sure makes the things feel a whole lot less like work.

I don't trust that most toilet tanks are built to withstand the weight of a grown-ass man, so this is something that I do not do.

My natural instinct is to slouch forwards in any position.

I went through a short lived phase where I thought it was hilarious and natural to AC Slater the toilet. Sit on it backwards a la spinning the chair around at the lunchtable, grip the tank and let er rip. Haven't done this much since entering adulthood, but it still seems like a fun thing to do if the mood strikes.

The toilet at work flushes automatically every 30 seconds when you sit on it unless you lean forward really far the whole time.

This angered me for the longest time until I finally figured out this was actually working out in my favor in a lot of ways.
