I want to ask every native speaker that currently lives in Spain, do people say "¡Cállate, que pareces radio!" ('Shut up, you sound like a radio!' - google translator) ??? I read in some reddit post about it and I want to know cause I'm writing a book where one of the characters is Spanish and I want it to be as real as possible, and if not, can someone tell me what similar phrase do y'all use? and I'd appreciate if you'd give me some other phrases you use in daily life. Again, I'm talking to people who currently live in Spain, or at least were there in the last year.
