Popping a pimple or zit can be quite painful. Doing the same with a quarter-sized cyst with presumably no anesthetics looks 100x’s more painful.
The person doing the popping is doing so, sans gloves (or any other protective equipment) making it hard to know if we should applaud them for bravery or condemn them for stupidity.
The best part about this? Onlookers asking what the pus was. It’s gross, what more do you need to know. What’s more, what were you expecting from something that’s essentially a suped-up zit?
