OP is on Mastodon. I checked the post there, and there’s absolutely nothing to imply it should be NSFW. Maybe some kind of disconnect between the software?

It’s crudely drawn images of an alkylating agent stuck to shit. I’m gonna go out on a limb and say that’s the whole joke. Like, no deep levels to this. I think it’s literally what you see.

Edit: This was meant to be a reply. 😢
