Faito dayo is a catchphrase associated with Honoka Kousaka, the energetic leader of the school idol group μ's in Love Live! School Idol Project. In Japanese, faito is borrowed from English fight and used to cheer someone on, while dayo adds a friendly, confident emphasis. Fans clipped Honoka's delivery and shared it in anime edits, reaction videos, and motivational compilations, where its short length made it easy to reuse. It remains popular because it captures Honoka's optimistic personality in a single, instantly recognisable cheer.
