Riven and Sona are both champions from League of Legends, the Riot Games multiplayer battle arena game, and a full AP Sona build turns the usual support champion into a burst damage threat. That contrast is why the clip circulates among League players, who recognize the setup instantly and use the drawn-out reaction to mark an unexpected kill or turnaround. Shared as a short standalone sound, it has become a handy shorthand in gaming edits and reaction videos, where a single vocal gasp can signal surprise faster than commentary.
