Mario Party is Nintendo's long-running party video game series, first released for the Nintendo 64 in 1998, in which Mario characters compete in board games and minigames. The start announcement became familiar to players through repeated play and later through gameplay videos, livestreams and short-form edits shared online. As clips of chaotic minigames and board moments spread on YouTube and TikTok, the opening voice became a shorthand cue for friendly competition. It remains popular because it instantly sets a playful, competitive mood without needing any explanation.
