The phrase comes from Jalen Rose, the former NBA guard who became a well known television analyst after his playing career. Clipped from his on air commentary, his short refusal began circulating on sports social media as a reaction to lopsided matchups and hopeless predictions, then spread beyond basketball into general meme use. Its appeal has lasted because the wording is instantly understood without context and the delivery needs no setup. Today it is used less as a sports quote and more as a universal shorthand for nope, not happening.
