The 'Get A Brain Morans' meme features a photograph of a man holding a picket sign that ironically misspells 'morons' while questioning the intelligence of others. The image surfaced in 2003 during a protest outside a St. Louis Cardinals baseball game, where a man held the sign to express his views on the Iraq War. It quickly became an internet sensation, serving as the ultimate reaction image to highlight hypocrisy, irony, or poor arguments. Today, it is widely used across social media to call out people who make arrogant yet factually or grammatically incorrect statements, making it a staple of internet debate culture.
