The sound a true idea makes after its thousandth repetition.

means The staleness of an idea or phrase that was once sharp but has been worn smooth by overuse.

from From Latin 'tritus,' past participle of 'terere' — to rub, wear down, or grind. The same root gives us 'attrition' (wearing down by friction) and 'detritus' (debris worn away by erosion). A trite phrase, literally, has been rubbed thin by too many mouths handling it.
