This is a bit gross but when you type the term "popping" on youtube, it will lead you to some popping white heads, pimples, etc videos. Ten years ago when you hear about popping it's all just about a soft explosive sound but now it's completely different. It's because of the strange popularity of popping pimples videos spreading on youtube and other social networking sites.

The Science Of Disgust

Popping pimples or cyst is pretty gross.

But it’s this exact factor that makes it so irresistible to some. In an interview with Salon, Daniel Kelly, author of the book Yuck!: The Nature and Moral Significance of Disgust, explained that repulsion is a trait that humans evolved to keep themselves safe from the dangers of contagious disease or infection.

“Disgust is a psychological component to this arsenal of protective weaponry,” Kelly said. “Instead of waiting until something gets into our system that we have to fight to push out, disgust helps us to stay away from objects and people that are likely to get us sick.”

Our ever present instinct to avoid things that disgust means that as a society we’ve devised a way to shield ourselves from common sources of disgust: morgues to deal the dead, hospitals to deal with the sick, sewage and sanitation to deal with waste and garbage. As a result, the instances where we will feel genuine disgust are few and far between. According to Kelly, it’s this desensitization which has allowed the rare, disgusting footage or experience to truly capture our attention.
