Waku waku is a Japanese expression for trembling with excitement, long used in everyday speech and in anime to show a character can barely contain anticipation. Short voice clips of the phrase spread through anime fandom on TikTok, Discord and soundboards, especially as fans shared cute reaction sounds alongside clips like Tuturu. Its brevity and clear emotion make it reusable far beyond its original context, so creators drop it under reveals, unboxings and happy moments where a single wordless reaction would feel flat, but two cheerful syllables say everything instantly.
