yubi yubi (inugami korone)

ゆびゆび

Virtual Youtuber Inugami Korone's greeting and catchphrase. Literally means "Finger, Finger!".
This has become a running gag in her stream, in which her viewers have to "offer" their fingers to Korone at the beginning of the stream, being returned as rotten ones at the end of the stream. Korone herself later commented that this recurring gag was spontaneously created during her debut stream with no specific reason whatsoever.

The tag relates to both the catchphrase being present in the image/commentary, or to depictions of severed fingers.
