In mahjong, the characters suit, also called cracks or wan, runs from one to nine, and wu wan is simply the five tile. Calling a discard aloud is standard table etiquette in many Chinese and Japanese mahjong circles, keeping the game legible for all players. As mahjong games moved online and into streaming, these little table calls became familiar meme audio, especially among fans of mahjong anime and browser mahjong games. Short tile calls like this one now circulate as soundboard clips used for game-night humor, reaction memes and edits that nod to mahjong culture.
