Bonesmasher Ass

This ass read that stressing the facial bones makes them denser, and heard, apparently, a call to violence. So now they hit themselves. On purpose. With objects. For the jaw. They call it bonesmashing, and they will explain the science to you, which is not science, while holding a small hammer they consider a grooming tool. There is no dentist on earth who has endorsed this. But the commitment is genuinely awe-inspiring, in the way a car crash is. A man improving his face by declaring war on it, one questionable tap at a time, undefeated by common sense.
