Usually spelled like”GYAAATTTT”
“Gyat” is a term created by a streamer named YourRage aka (RAGEYPOO) it is an aberration for “God Damn” and is usually only used when you see a fat booty bitch with the cakes. You could also use it if the bih fine enough but it’s usually only used for seeing a fat/shaped ass.
the real definition is a funny way to say goddam when u see a fat ass or titties, popularized by one of the best twitch streamer's yourrage but kids today think kai cenat made it (no disrespect to one of the goats of twitch btw)
