Gadoer
A Gadoer is like a loudspeaker that never turns off and also never shuts up.
My brother is a Gadoer. He talks during dinner, at bedtime, and even in his sleep.
My mom called my little sister a Gadoer because she wouldn’t stop talking during the movie.
My neighbor is a Gadoer. He yells at the mailman, the trash truck, and even the clouds.
