The most disturbing thing I've seen in a long time has to be when I first was reading about Keffals on KF. The long title said something about him/her being a 'fart dominatrix' but nothing in the main thread seemed to elaborate. Curious, I hunted around and found the clip posted elsewhere. It had a spoiler tag that said 'NSFL, and you might die from cringe.' For some reason I clicked on it and... yes that was an apt disclaimer. I expected to see maybe Keffals in underwear farting or something, but instead what I saw was 'her' entire post-op gash on full display, and close up.
I seriously wish I could give myself some brain bleach for the couple of occasions that I've seen that on KF. Another thread about a post-op trans woman had her 'farting defective' neovagina on full display that I somehow saw too. It reminds me of a raw chicken, just this giant gaping hole that looks more like a real axewound than a vagina.
