Woomy became known through Splatoon, Nintendo's ink shooter released in 2015, where Inklings use it as an excited vocalisation similar to a cheer. Players adopted the phrase in chat, fan art and videos, turning the in game noise into a shared fandom shorthand for feeling hyped. Short clips of the shout later circulated on soundboards and in meme edits, often sped up or layered for comic effect. It remains popular because Splatoon fans recognise it instantly, while other viewers still hear a clear burst of joy.
