Trivia

 * "Clipping" is a term in computer graphics for intersecting objects, especially in ways they shouldn't be intersecting. It can refer to harmless graphical anomalies, as well as gameplay objects (such as players and walls) colliding in detrimental ways.
 * More specifically, this option references how video game speedrunners will use glitches to "clip through" obstacles and walls, usually to bypass some levels or access areas early. These techniques are often very difficult and precise, requiring timing within 1/30th or 1/60th of a second &mdash; which is called "frame-perfect" timing.
