The 'Holy Music Stops' meme features a medieval knight, typically a crusader, looking visibly shaken or disgusted, implying that something 'sinful' has just occurred. It is a variation of the 'Jazz Music Stops' format and gained massive popularity on platforms like Reddit and Tumblr around 2018. The image often originates from art related to the game Chivalry: Medieval Warfare or generic stock illustrations of crusaders. It is used as a reaction image to highlight degenerate behavior, dark humor, or any situation where a moral line has been crossed, suggesting that even a man of faith is horrified by what he just witnessed.
