LOS ANGELES, Calif. /ScoopCloud/ -- Will the real Stan please stand up? Before James "Slim Jimmy" Guiltinan knew that Eminem's "Stan" had become a dictionary word defined as a sort of super, but sometimes obsessed fan, he'd written one of his first two rap songs, as an Eminem "salute." The slang definition of "stan" likely originated from Eminem's song and music video "Stan."
