Chewing gum is a confection designed for oral enjoyment, typically made from gum base, sweeteners, and flavorings. It's a low-stakes comfort item that most people chew casually throughout the day. The flavor is temporary; the experience is brief. It's one of the most innocent human consumption habits, ranking below food in nutritional significance. The choice of gum flavor is purely personal preference: mint, cinnamon, fruit flavors, etc.

Then this fact introduces a shocking substitution: Chuck Norris's preferred chewing gum is bullets. The image is darkly absurd: him with a jaw full of ammunition, thoughtlessly mastication on lethal projectiles. The fact doesn't explain why. Is he eating them for sustenance? Is he turning them into something else? The lack of explanation is key. The detail is presented with the same casualness as someone describing their gum preference—"I like spearmint"—except the preference is for ammunition.

What makes this work is the cognitive dissonance. Chewing gum is the most peaceful of habits. Bullets are instruments of violence. Conflating them creates an image that's simultaneously mundane (just chewing) and apocalyptic (chewing ammunition). The fact works through juxtaposition, treating the absurd as routine. He doesn't eat bullets; he chews them. The choice of verb preserves the mundanity while introducing the lethal element.
