Mobile Legends: Bang Bang is a mobile multiplayer online battle arena game developed by Moonton and released in 2016, where two teams of five heroes battle to destroy the enemy base. First Blood is a long-standing MOBA term for the first kill of a match, and the game marks it with a distinctive announcer voice line. As Mobile Legends gameplay clips spread on YouTube, TikTok and short-form edits, the short announcement became a recognisable shorthand for an opening advantage, and creators still reuse it to signal that a match has truly begun.
