like a broken record
Like a person or thing that repeats itself over and over again. Likened to vinyl records that when severely scratched (i.e., "broken") can loop over the same recorded segment endlessly. I feel like a broken record having to tell you this each day, but please clean your room!
like a broken record
To repeat and repeat ad nauseam. Vinyl records, as those readers who remember them will recall, have spiraling grooves in which the photograph needle picked up the sound. When a groove developed a crack or other imperfection, the needle became stuck and the sound kept repeating until someone moved the phonograph arm to the next groove. The expression was applied to anyone who repeated a remark or request over and over until it sounded like a broken record . . . a broken record . . . a broken record.
