Gyatt. Noun. Singular. IPA Pronunciation: /ɡjæt/
Slang/brainrot term for someone's butt or ass, depending on the context. Originates from a corruption of the term "Got damn!", as would be said when seeing a large tushy. Eventually, this evolved into a more emotive version, "GYATT DAMN!", and then to gyatt.
See also: "Sticking your gyatt out".
I hate I had to make this but I'm Gen Z and therefore obligated to. I've kept it short & sweet on purpose.
