Warning:The following video is really gross. Definitely NSWE (not safe while eating). But I made the mistake of watching it, and now I want to know what in the world it could be showing.
What happens is that you see a man's face getting scrubbed with a piece of cotton. And then tiny worms begin to ooze out of the man's pores.
The most sensible theory to be found in the YouTube comments (which I don't recommend reading) is that the video shows some kind of pseudo-medical treatment (for what, I can't imagine), in which worm eggs are smeared on the man's face with the cotton, and then the worms seem to emerge from the guy's skin. Sounds plausible. Any other theories?
