Rin song from Vocaloid! In Shiratori, players take turns naming off nouns that end with the final kana of the previous word. However, the player who names a word that ends in "n" loses, because no Japanese words start with "n", so the game is over. So what happens in the song is that she tries to start the game by playing off the word "shiratoRI", except she picks the word "RIn" [her own name], ending in "n", so she loses! Additionally, Janken is a Japanese rock-paper-scissors game - players say "jan-ken-pon" during gameplay, and the phrase "aiko desho" is said when there's a tie.
