Salieri is Antonio Salieri as an Avenger class Servant in Fate/Grand Order, the mobile RPG from the Fate series. His strained uwoooo cry is used in game as a damage reaction, especially around Noble Phantasm attacks, and short clips of it were ripped and shared on soundboards as a standalone reaction. Players and editors began using it outside the game for any overblown loss, painful pull or dramatic injury joke, because the theatrical delivery is instantly recognisable to Fate fans while still reading as pure anguish to everyone else.
