Nutty as a fruitcake意思

"Nutty as a fruitcake" is an English idiom that means someone is crazy, eccentric, or overly enthusiastic, similar to the way a fruitcake is often studded with nuts. It implies that the person's behavior is as unpredictable and perhaps as excessive as the nut-filled cake. The phrase is often used humorously or affectionately to describe someone who is not just a little bit nuts, but significantly so, in a way that might be considered endearing or amusing.
