Nico Nico Nii comes from the anime franchise Love Live! and is associated with the character Nico Yazawa. The phrase became widely shared through anime fandom, reposted clips and reaction edits, then spread beyond that niche into general meme culture. Its staying power comes from how instantly recognizable and exaggerated it sounds in just a couple of seconds. Online, people use it both sincerely and ironically, much like other short anime catchphrase sounds such as Ara Ara.
