Is this danced referenced from something?

Is the dance 追加ロビーアクション２７ referenced from somewhere? I have heard people say Hatsune Miku but idk

[Ezodagrom]

It's one of the dance lobby actions from PSU.

[Shirai]

If it's the dance I'm thinking of, then it's not based off of Miku. Since that dance came before her, it's from PSU.

[BIG OLAF]

Yes. Both of the non-standard 'dance' tickets have been the four PSU dances.
