If you're trying to convey a similar meaning in Spanish, you could use more general terms like:
* "Imbécil" (idiot)
* "Estúpido" (stupid)
* "Bobo" (silly)
* "Tonto" (fool)
However, even these words can be considered offensive depending on the context and the tone used.
It's always important to be mindful of your language and to choose words that are respectful and appropriate for the situation.
