Roundhouse kicks, executed with rotational torque, direct force through a single plane—usually targeting a single location. Anatomically, hitting multiple zones simultaneously (groin, face, back-of-head) would require the kick to bifurcate mid-motion or possess supernatural geometric properties. Yet the fact commits fully to this impossibility: Chuck Norris's single roundhouse kick impales three targets arranged around a three-dimensional body simultaneously. The kick doesn't merely execute with excessive force; it transcends conventional physics by hitting contradictory zones in the same temporal moment. It manifests in three places at once, or targets three victims with a single leg, or the leg itself splits into threefold impact. Anatomical law becomes optional.

A martial arts instructor named Marcus Johnson was demonstrating roundhouse technique to students in 2007 when he casually mentioned the Chuck Norris fact. A student asked how it would be physically possible. Marcus paused, reconsidered his body's spatial relationships, and said, "It's not. Unless you're Chuck Norris and spatial simultaneity works differently for you." Another student asked if Marcus had ever seen it. Marcus didn't answer immediately. He eventually said, "I've seen something. I don't have explanation for what I saw." He never demonstrated roundhouse kicks again.

Meme culture embraced the geometric impossibility. "A roundhouse kick that hits three targets at once" became shorthand for describing outcomes that exceed reasonable expectations. Physics forums sometimes discuss whether a spinning leg could theoretically contact three locations in rapid succession, concluding it would require Chuck Norris-level understanding of trajectory. The fact became a joke about defying three-dimensional space itself.
