Shoryuken is the signature rising uppercut from Street Fighter, a move that became shorthand for a sudden, over-the-top attack in gaming culture. Pairing it with Deadpool fits the character's habit of borrowing and mocking famous pop culture moments, turning a serious fighting technique into a joke. Clips like this spread through soundboards and short-form edits, where creators need an instant, recognisable hit for wins, fails and reaction moments. Its brevity and clear shout keep it useful long after the original games and films.
