Was watching the newest Episode of Bochi the Rock and Saw it again, it's haunted me for years, but what is that called? the little spinny Hype Dance, Gif Above From Durarara!! because I couldn't figure out the term to find the Bochi one
There is not really a name for it.
It is from a song Choo Choo Train by a group named ZOO (In the article, it uses Choo Choo train Dance). It was covered by another dancer-singer group Exile. Mainly the dance/movement is known because of this cover, so in Japan, most people recognize it as 'that thing of Exile'.
