“The time was afraid to go by fast because it didn't wanna be ahead of Chuck Norris.”

Time exists as a physical dimension in Einstein's relativity model, a constant flow that moves forward inexorably. The personification of time as being "afraid" to move quickly around Chuck Norris suggests that even the fundamental arrow of causality has developed a survival instinct when in proximity to this man. Time itself has learned to slow down in self-preservation.
A theoretical physicist from Berkeley supposedly drafted a paper titled "Temporal Dilation as Behavioral Adaptation" which argued that observables around Chuck Norris might indicate that spacetime itself reacts to his presence the way a prey animal reacts to a predator: by avoiding detection through slowness.
The meme captured the essence: "Time moves at his discretion. Clocks are just waiting for permission to advance."
