An acronym coined by Britishchef Gordon Ramsay. It stands for, "can you stop slapping your meat?" In one of Ramsay's TikToks, he reacts to a cooking video, which ultimately causes him to utter this sentence. It eventually went viral, following "SMYW", also coined by Gordon Ramsay.
A hardo is a person who tries extremely hard at everything. Most times a hardo will try very hard at things that do not require excessive effort. For example, sports practices, gym class, etc.
Wow did you see Jack at practice today? What a hardo!
