The 'Triggered' meme emerged in the mid-2010s, originally mocking the concept of 'trigger warnings' used in online spaces like Tumblr. It evolved into a high-energy reaction image, often characterized by a radial blur effect, intense shaking, and a distinct red '[TRIGGERED]' bar at the bottom. While it started as a controversial jab at political correctness, it quickly transitioned into a broader internet shorthand for any situation involving extreme, often hyperbolic, annoyance or shock. Today, the meme is frequently used to highlight minor inconveniences or absurdly intense reactions to everyday events, making it a staple of social media commentary and GIF culture.
