f'gyeah
when your mouth is too full of junk food or too lazy to talk but you still yell fuck yeah like a loud idiot
I just ate three burgers and said f'gyeah so loud my dog ran away
He was too full from pizza to speak, but he still did a f'gyeah in the middle of the game
She said f'gyeah while chewing a whole bag of chips like it was a challenge
