can't honestly say I've heard someone say "piss fetish" before.
People don't say "shit fetish" they say "scat fetish" although to be fair that usage stems from "scatological" which in turn has a Latin etymology. But that's beside the point.>common knowledge
to be fair, I originally used the term "niche knowledge" but I think for people who are well acquainted with the internet, and especially people who browse 4chan, this truly is common knowledge.
For example, do you know what a "trap" is? When people say "trap" on 4chan, it's commonly understood that this could just as likely denote an androgynous cute male or pre-op trans woman, but to the rest of the world this meaning is usually lost.
So, we have to consider the context, here. Sure, /co/ is pretty much a normie boards, but it's still 4chan, and you should just accept that you are most certainly in the small minority of ignorant fucks who wasn't familiar with the term "watersports" in 2017, let alone the minority of white people with access to the internet. >this is assuming that you're white>I have a sneaking suspicion you are shitskin
