Nico Nico Nii is the signature catchphrase of Nico Yazawa from Love Live School Idol Project, where the character strikes a pose with her hands above her head while announcing herself. The line became one of anime's most quoted meme moments and has been imitated by cosplayers, idols and streamers for years. Filian, a VRChat variety VTuber known for chaotic comedy, made her own rendition a running bit with her audience, and clips of her shouting it circulate widely as reaction memes.
