lol at someone losing an eye because a coin was thrown at them from 100 feet away. That's some surgical fucking precision coin chucking there.
Even assuming it hits you in the eye, it's not going to dislodge it from your head. It's a fucking coin, not an ice pick.
You can question whether it's worse to be called names than to have small hard objects thrown at you from a distance. But don't try to pretend any of those objects posed a serious threat to that guy's health. He wasn't going to wake up in the hospital with one eye because he got hit by a £1 coin thrown at him.
