I watched a video by Plagued Moth today, where he shows that people use parts of suicide/gore videos which are put into e.g. TikTok's of cute animals, or Christian music songs on YouTube. Have you ever met something like that in porn movies? Or maybe just a "regular scary face" jumpscare?
So that's what you call it... It wasn't porn per se but let's just say it was a sexy video on YouTube where in the middle of it this woman turns into a demon. It put me off looking at sexy videos on YouTube for months.
