The chant comes from Nico Yazawa, a member of the school idol group μ's in Love Live, who uses Nico Nico Nii as her playful self-introduction and signature pose.

It later spread further on TikTok and YouTube, often paired with cute or confident character moments. Its lasting appeal comes from that mix of nostalgia, humour and instantly recognisable anime energy.
