The image is a reddit post with the following text (automatically transcribed):
I remember I got into an argument on reddit awhile ago with a person over Italian food. It got to the point they were following me into other subs to harass me. I clicked on their profile to block them and their most recent post was them drinking their own piss on r/piss. At that moment I realized I had spent so much pointless time arguing about the taste of food with someone who drinks their own piss as a hobby. This site is a shit hole.
Pissing into the sink is hot… that was the kink, right?
I mean really, they’re both strong candidates for misbehavior depending on context. I couldn’t care less if someone peed in their own sink (and hopefully rinsed at least after).
Once you’re peeing in a public restroom’s sink… You’re almost certainly risking indecent exposure, which is misconduct.
Sounding, it’s mostly about consent. It’s weird enough that I’d argue it definitely requires consent to even see it in an adult context. lol
