1. Go to a large, open field with 4+ friends. Bring large cardboard boxes that, if placed on the head, would reach down to one's lower torso/waist.
2. Everyone get into a large circle, facing each other
3. All participants place a large cardboard box on their head. Brace front of the inside of the box with your arms, so that if you are in a full-on collision, you will not get a head injury.
4. SPRINT IN ANY DIRECTION AND HOPE YOU HIT SOMEONE!
The intenseness of this sport is from the adrenaline of never knowing when you're going to be hit. Peeking out of the bottom of your box at times of rest is permitted AT YOUR OWN RISK.
I am not liable for any injuries that happen due to this definition. :D
