Holy cow, I think I've got it; it sounds like "geechee", and it's an actual term used about Blacks/Africans who lived in South Carolina. Frazier's from South Carolina - https://www.urbandictionary.com/define.php?term=Geechee
He said he was a geechy. He was insulting Frazier. Geechy referred to plantation slaves who spoke with a broken English dialect. He basically said he was a plantation slave with a poor vocabulary. It was Ali being racist, right before he saw the giant stuffed gorilla, called it Frazier, and started hitting it.
