PPAP, short for Pen Pineapple Apple Pen, was released in 2016 by Japanese comedian Daimaou Kosaka performing as the character PIKOTARO in a leopard print outfit. The video was uploaded to YouTube and spread worldwide after its repetitive lyrics and dance were shared widely on social media, including a notable boost when Justin Bieber called it his favorite video. It later charted internationally and became one of the defining viral songs of that year. The short intro remains popular because it instantly signals the full routine in just a few seconds.
