I'll eat my hat Meaning in English
expression
Definition
This is a humorous way to say you are absolutely sure something won't happen. You use it when you strongly doubt something, not because you really plan to eat your hat.
Usage & Nuances
Very informal and humorous; used mostly in British or older American English. Not literal—no one actually eats their hat. Common after a statement you believe definitely won't come true: 'If X happens, I'll eat my hat.' Do not use in formal writing.
