Popuko is one of the two main characters in Pop Team Epic, a Japanese comedy series known for its chaotic, sketch-based humour and exaggerated reactions. A lemon-licking moment fits that style perfectly, turning an everyday sour taste into a memorable visual gag. As a short standalone clip, it spread through soundboards and meme edits, where creators could reuse the reaction without needing the original scene. It remains useful because sour faces are universally recognisable, making the sound work in food videos, challenges, and comedy edits across platforms.
