A place where polyamorous couples settle down and do polyamorous stuff. It can be a house, a treehouse, an apartment block, a single room or an RV.
Are there any differences between these places? Absolutely not. All of them house these people and all of them have the same environment to offer.
Just imagine the stench of days-old sweat lingering inside... The heat... The rising jealousy of everyone inside this place... The madness in the air... Sounds worse than an actual cesspit if you ask me...
And some people openly say "wE nEEd tO nORmaLIzE PoLYAmORy" like it's a good thing...
May Providence guide them to a better path...
Dylan: Hey there, bruh.
Romeo: Yes?
Dylan: Would you mind if you join me in my house this evening? I have something special to show you.
Romeo: But my wife's expecting me to-
Dylan: Don't worry, she'll be fine.
A few hours later...
Dylan: Welcome! Join me inside so that I can introduce you to my partners.
Romeo: Wait... Did you say... Partners..?
Dylan: Yes. I'm polyamorous, and I'm living with my 4 partners in this house for 4 years. Sounds great, right?
Romeo: Absolutely not. This place looks like a moral cesspit for me.
Dylan: What!?
Romeo: What's the word... Uhh... Yes! It's called a polyamorous cesspit.
Dylan: Who told you that!?
Romeo: My wife. She described it for me and she's absolutely right about this. The stench, the odd feeling, the hidden jealousy and everything.
Dylan: *MICROAGRESSION* Shut up you CIS WHITE MAN!!!! SHSJJWHEWHDJWHAHAJ!!!!!!!!!
Romeo: What an idiot.
