Kuka
The word "kuka" means "trash bin", but it reflects a tongue-tied person (usually not a mute person, but somebody who shy or doesn't know what to say in that situation.
"Megkukultál?" = "Did you become a trash bin?" means: Did you become mute? (Almost the same question: "Elállt a szavad?" = "Are your words stopped?")
