Boomboxing 

To stalk or otherwise reaffirm your love to someone who actually loves you, but can't or won't be in a relationship with you right now. To have trouble letting it go.

From the scene in "Say Anything" where John Cusack stands outside his ex-girlfriend's window holding a boombox that's playing Peter Gabriel's "In Your Eyes."

Stop boomboxing me, okay? You had your chance, and you blew it.

BoxBoxing 

The art and/or sport of blindly running into people with a cardboard box on your head.

Howto:

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

While Adam, Daniel, Todd, and I were boxboxing last weekend, Adam hit Daniel and Daniel was so un-prepared that he was airborne for five feet.
