Basically, you laying there dead on the pavement with a white chalk outline of your dead carcass due to a large caliper weapon(like a .44) used to blow your brains out with one hollow tip. Leaving you lying there for everyone to see with your Helmet (slang obviously for head) Hung or Hanging in a Hung position.

"Bicycle Helmet Generation", a term crowned by American Standup Comedian Bill Burr used to describe Generation Z (Zoomers). The term comes from the need to overcompensate for safety, and thus sacrifice the fun that the activity originally had. Which is something that most people in Generation Z had to grow up with, usually enforced by their parents. This obsession with over-the-top safety is a key characteristic of what defines the generation that's well known for being too sheltered. This is characterized by Byclicle helmets in which most children are forced to wear for "their own good". This being a key sample where excessive safety measures have taken the place of fun, in what should have been a free and spontaneous activity. This is also characterized by overprotectiveness, and a parent/guardians' general fear to give their child the slightest bit of autonomy.
Why were what should have been the fun physical activities of my childhood so boring and vapid?

I guess that's because I grew up in the Bicycle Helmet Generation
