The Shoryuken comes from Capcom's Street Fighter series, where it is the signature rising uppercut of Ryu and Ken. The move and its shouted name became famous during the arcade boom of the early 1990s, when Street Fighter II turned fighting games into a competitive phenomenon. Its short vocal cue travelled beyond arcades into tournaments, Let's Plays, reaction videos and meme edits, where it signals a dramatic reversal or knockout. Decades later it remains shorthand for a powerful comeback, instantly understood even by viewers who have never played the games.
