Gyatt

Gyatt is a term that originally had a meaning from Kai Cenat streams, used as an abbreviation of "god damn", often used to comment on the bodies of curvy women. Over time, the meaning has devolved into simply being anoher word for your bum, common in meme communities, and used as a descriptor for predominantly women.

"Oh my gosh she has a giant GYATT!!" - an infant probably.
