The 'Moka Chan Oshiete Kureta Irona Mita' meme, commonly known as the Horse Speaking Japanese meme, features a close-up of a horse appearing to lip-sync to a high-pitched Japanese audio clip. The sound bite originates from the character Moka Aoba in the 'BanG Dream!' franchise, specifically a cute line about things she has been taught. This meme surged in popularity on TikTok and YouTube during 2023 and 2024, becoming a staple of surrealist and 'brain rot' humor. It is typically used to represent a state of mind that is nonsensical, overwhelmed, or deeply irony-poisoned, leveraging the uncanny valley effect of the horse's mouth movements paired with high-energy anime vocals.
