A game in which you seek out people riding bikes and attempt to throw a football (throw anything really, but preferably a football) at the bike wheels in order to get them to fall. A game along the lines of throwing sticks in front of online skaters a la Big Daddy.
"Do you know what bicycle skeet shooting is?"
"Are you going to shoot me on my bike?"
"No, I'm going to throw a football at your bike wheels."
"You're a dick. That sounds like such a redneck game."
