This is another one of those that’s fascinating because of the quantity of goo that keeps coming out.
The YouTube description says the person is popping a blackhead on the thumb, and if that is a blackhead, it’s the blackhead from hell. One little pop turns into a stream of cheese, followed by what looks like pus and blood. And, it had to hurt, because the guy on the video groans in obvious discomfort.
With a thumb that bad, it must have been hard to hold on to anything.
