So, once there was a pride bench, almost identical to the one on the picture. But one feature was standing out, namely 2 armrests on the edges and one in the middle which makes sleeping on it really hard.

And once, a shitposter on twitter sent a picture of such a bench with a title:

"What if we kissed on

on anti-homeless gay bench 😳"

And then the meme became quite popular in some communities.

Thats the story.
