Booyah is one of the signature communication calls in Splatoon, Nintendo's colourful team-based shooter where players control Inklings who battle by covering turf with ink. In multiplayer, players use the call to celebrate a successful push, praise a teammate, or rally the team before a final attack. The short, upbeat shout became a familiar part of Splatoon matches and gameplay videos, and it continues to appear in edits and reaction clips because it instantly signals a win, a comeback, or shared excitement without needing any explanation.
