Wheel hop happens in nearly every FWD car if you accelerate hard enough. When you hit the gas hard, the wheels(or wheel) grip and move forward in the wheel well, changing the alignment(toe) of the wheels. This causes a loss of grip, and the wheels spin. During the wheel spin, the wheel moves back to it's original position. The car regains grip and the process starts over.
