The line comes from Idiocracy, the 2006 dystopian comedy directed by Mike Judge, in which an average man wakes up 500 years in the future to a dumbed-down America. Inside a gigantic Costco, greeters and loudspeakers repeat the mantra 'Welcome to Costco, I love you' with blank corporate warmth. The scene became one of the film's most quoted moments as Idiocracy gained cult status through memes and streaming. Today the clip circulates as shorthand for satirizing consumer culture and overly cheerful retail branding.
