NSFW Warning. For the uninitiated: Back in the early internet (2006-2009), there was a video a man posted (somewhere, but it was circulated on 4chan) of himself slowly lowering his ass onto a Mason jar, into his rectum. The glass shattered mid way through, and blood streamed out of his asshole. It was horrific, and memorable. Kind of like 9/11 part two… Never forget.

Bodies of Water

Looks AI. It isn’t, but looks that way.

OP posted a video in a comment a bit further down.
