The most recent being the jeans trend. It was funny, I get why everyone enjoys a good shitpost. Some of the shitpost are top quality and fun for all to enjoy. But after a couple of days the shitposts just turn to shit posts and its just upvote farming low quality content and kills the joke.
I agree most of these verge on dad jokes at best and maybe go on way too long. I will say l genuinely enjoy to see the camaraderie and spike in participation.
