It’s simple, if it jiggles, it’s fat.

The line is a blunt, bodybuilder’s rule-of-thumb: visible “jiggle” is treated as an unmistakable sign of excess body fat. Its force comes from its simplicity and shock value—reducing a complex topic (body composition, health, aesthetics) to an easy sensory test. Read as motivational rhetoric, it reflects a hard-edged training culture that prizes leanness and discipline and uses humor or provocation to spur action. Read critically, it also exemplifies how fitness talk can oversimplify physiology and encourage harsh self-scrutiny by equating normal softness or movement with “fat.”
