This comes from highschool football(American) when the extra point is about to be kicked. Some highschools use a tee to hold the ball after it's snapped, although most do not. If a kicker doesn't want the tee, he asks his coach to remove it and kick it as it was meant, off the ground.
If you can imagine a car on jackstands and you crank it hold the throttle wide open and then someone pushes the car down off the jackstands and it hits the ground spinning and all over the place. Well this is how we descibe how we will start an afternoon before a big party
When one bro/brodette is angered or irritated by another bro/brodette and to come at the other bro, said bro kicks his flips off to initiate the bro fight.
