If you're one of those people who loves nothing more than watching a video of blackheads being squeezed out of a bulbous nose, you might have been at the receiving end of judgemental comments.
Hey, you've even judged yourself from time to time.
"Why can't I stop watching this?" you ask yourself, gazing at a clip of an cyst erupting in a shower of pus.
But you're not alone. So popular are these videos, people are actually making a living out of them.
Sandra Lee, also known as Dr Pimple Popper , has a whopping 1.1million subscribers to her YouTube channel where she posts gruesome videos of extractions.
Why do we love them so much?
What's the fascination with these gross clips? Apparently it's all to do with our love of danger.
While that might not sound immediately obvious, just hear us out...
Daniel Kelly, assistant professor of philosophy at Purdue University, told Cosmopolitan : "It's the same kind of thrill people get from, say, riding a roller coaster or bungee jumping — it activates the experience the typically comes with a real kind of danger while actually being protected from the harmful effects typically associated with those situations.
Kelly, who also wrote a book on the nature of disgust, added: "One of the main functions of disgust, the heart of this particular emotion's primary job or core mission, is to protect us from infectious diseases."
Do you like watching pimple-popping videos?
1000+ VOTES SO FAR
Nina Strohminger, author of The Hedonics of Disgust , told Cosmopolitan: "I don't think there's anything straightforwardly masochistic about it.
"Rather, negative sensations are interesting, particularly when you're in a context where they can't hurt you.
"You're probably not going to step in dog s***t just for the experience, but maybe you'd click on a link to watch someone else doing it."
While some people are more squeamish about these things than others, those of us who find ourselves watching the videos must find it too hard to resist our curiosity about something so gross.
So, there you have it. We love to feel those negative emotions that can't hurt us.
