I believe the correct answer is: Iscathamiya.
Iscathamiya meaning "to walk like a cat" is a
derivative of the mbube vocal style developed by singing group Ladysmith Black Mambazo. The
term is derived from the Zulu verb “cathama” which means walking softly. The isicathamiya
choirs are traditionally all male choirs.
Most likely a wolf would lie down belly up to
show submission
This is a friendly amd submissive gesture because when its doing this its trying to look smaller
It'll also roll over to show a dominant wolf that
it is helpless and not aggressive
