In Japanese, this specific position might be called a reverse inari-otoshi (falling inari). If you’ve ever seen an inarizushi up close, you may understand why. It’s usually performed on an unsuspecting high school friend who is sleeping face-up, and does not make you automatically hated among your peers, however disturbing the imagery might be (this is all hearsay; I didn’t even go to high school in Nippon).
Say it three times with me: Inariotoshi, inari-otoshi, ??????
That is your cultural baggage of the day; some things cannot be un-read.
