The line comes from the 2005 South Park episode 'The Losing Edge,' where Randy Marsh keeps picking drunken fights at his son Stan's Little League games and uses the excuse whenever police confront him. A clip of the scene circulated on YouTube and forums in the late 2000s before becoming a standard reaction quote on Reddit and in meme edits. Its appeal lasts because the wording works out of context, turning any minor rule, moderation decision or refusal into a mock-serious defence of freedom.
