The phrase comes from Anchorman, where Brick Tamland delivers it with complete sincerity, and it later found a second life in the moth meme, in which moths are shown as helplessly drawn to bright lamps. Shared across social media as a reaction clip, it became shorthand for irrational affection for an ordinary object. Its appeal has lasted because the line is short, instantly recognisable, and easy to drop into edits about lights, moths, or misplaced enthusiasm.
