The 'Woomy' meme stems from a specific voice line uttered by the Inkling Girl in the 2015 Nintendo game Splatoon. When players use certain in-game signals, the Inkling Girl makes a sound that fans phonetically interpreted as 'Woomy.' This cute and catchy vocalization quickly became the unofficial mascot phrase for the franchise, spawning countless remixes, fan animations, and reaction images. In the meme world, it is frequently used as a cheerful greeting, a sign of victory, or simply to represent the chaotic yet adorable nature of the Splatoon series and its dedicated fanbase.
