The 'Y'all Can't Behave' meme originated from Reddit, specifically as a common moderator notification used when a discussion thread becomes too toxic or controversial to manage. The phrase 'Locked because y'all can't behave' became a shorthand for institutional frustration with online discourse and the need to 'punish' a community by removing their ability to comment. Visually, the meme often features the yellow 'locked' padlock icon or a screenshot of a moderator’s stickied comment. It is widely used across social media to ironically react to chaotic arguments, controversial hot takes, or any situation where a group of people is acting out, effectively serving as a digital way to 'shut down the room.'
