This image became a meme recently and finally got an entry on KYM last weekend. It's been making rounds across Ywitter and Instagram in various forms.
The shocking nature of the gif has KYM denizens questioning humanity, probably brought to the article after seeing the edits and 'shops of the image resurging across social media.
It's properly tagged "guro", so you can blacklist it.
It's pretty clear that Ari yo was just joking, especially with the quotation mark. I think Ari yo might have been referencing a meme commonly seen on reddit.
