Angguk is the word for a nod in Malay and Indonesian, the opposite of geleng for shaking the head, and the doubled form angguk angguk is how the gesture is described in everyday speech and children's songs. Online, the phrase became a handy shorthand for enthusiastic agreement, and short clips repeating it spread through meme pages, chat audios and TikTok edits. Creators keep reusing it because the meaning is clear even without context, and the repetition turns a tiny gesture into a recognisable punchline for yes moments.
