Has anyone else ever BOTTLED UP PISS for absolutely no reason as a youth?

So the other day, my younger half brother was telling me a funny story about how built up quite the collection in his room before moving out.

I laughed and told him me and a good friend of mine had done the same, as teenagers, we send each other pictures of our collections to see who could build the most impressive catalog of urine.

I can’t help but wonder in retrospect if this is something male teenagers do, either because they find it funny, or they just want to have a better look at how dehydrated they are.

Or maybe there’s some kind of mental illness attached to this.
