The 'Ayaya' meme originates from the Japanese slice-of-life anime series Kiniro Mosaic (Kinmoza). The specific scene features the blonde, energetic character Karen Kujou mispronouncing her friend Aya Komichi's name as a rhythmic 'Ayaya! Ayaya!' while excitedly gesturing. This clip gained massive traction online, particularly within the anime and rhythm gaming communities like osu!, where it was turned into countless remixes and long-duration loops. In modern internet culture, the meme is synonymous with high-energy enthusiasm and is frequently used as a Twitch emote or a playful way to greet fellow anime fans. Its enduring popularity stems from Karen's infectious personality and the catchy, repetitive nature of her shout.
