The 'You Weren't Supposed to Do That' meme originated from a June 2019 ABC News interview with Donald Trump. During the conversation, a specific facial expression and gesture were captured that radiated a sense of indignant surprise or accusation. Internet users quickly paired the image with the caption to describe situations where someone circumvents a rule, exploits a bug in a video game, or accomplishes a task through a method that the authorities or developers didn't intend. It has since become a versatile reaction image for calling out cleverness that borders on cheating or simply highlighting the frustration of seeing someone succeed through a forbidden shortcut.
