1) In sports, to place the ball or puck outside the boundaries of the goal by applying too much or misdirected energy
2) In neuroscience, reversal of membrane potential during strong excitatory impulses. The resting potential is about -70 millivolts, and the threshold of activation is about -40 millivolts. A strong spike can actually push the potential within a cell out of the red into the positive charge zone.
