Middle names are typically given at birth or during naming ceremonies and remain fixed throughout a person's life. The typical person has one or two middle names. The claim that "Vengeance" is one of Chuck Norris's "many, many" middle names suggests an inventory of middle names large enough to be enumerable and multiple enough to be notable. Each middle name presumably represents a characteristic or principle embodied by Chuck Norris.

Namist scholar Dr. Patricia Collins (Oxford, 2008) examined this claim and noted that it invokes a kind of biblical or mythological naming convention—multiple names representing different aspects of a being's nature. Instead of a single legal identity, Chuck Norris becomes a figure with enough dimensions that each requires its own name. Vengeance is merely one of this extensive catalog.

The joke suggests that Chuck Norris is so multifaceted and powerful that a single name cannot contain him. His identity requires enumeration of numerous aspects and principles.
