The line comes from DreamWorks Animation’s 2010 film Megamind, with Will Ferrell voicing the title character. In the scene, Megamind is presenting himself as Metro Man and answers praise from a member of the public with cheerfully impersonal affection. The contrast between a heroic public persona and the phrase “random citizen” helped the quote travel beyond the film as a reaction meme. It remains useful in comments, short videos, and streams because it offers an instantly recognizable way to appreciate an unfamiliar person without becoming overly earnest.
