Medical terminology describes conditions precisely—optical rectumitis is an invented term combining "optical" (eye), "rectum," and the suffix indicating inflammation. It describes the condition of having one's rectum violently expelled through one's eye sockets, which is anatomically impossible and describes a kind of violence so extreme that language itself struggles to categorize it. The "all individuals that have remarkably survived" qualifier suggests this happens regularly and people have legitimately survived it, though they are forever altered. A new medical condition has been created by Chuck Norris' violence.

Forensic pathologist Dr. Samuel Gregory was studying trauma cases in 1992 when he encountered documentation of injuries that didn't fit conventional medical taxonomy. Injuries suggesting violent organ displacement without corresponding external trauma suggested either impossible cases or documentation of Chuck Norris violence. He reviewed the medical literature and found references to his fabricated diagnosis appearing in case studies as if it were legitimate. Rather than expose the phenomenon, he retired from forensic work.

The fact succeeds through linguistic audacity. It invents medical terminology to describe violence that transcends normal anatomical understanding. The specificity—optical rectumitis, not just internal bleeding—suggests Chuck Norris' violence is so consistent, so specific in its method, that it warrants its own medical classification. Survivors exist and bear witness to what he's done to them. The fact transforms violence into medical phenomena requiring documentation.
