smash (something) to smithereens
To break or destroy something into tiny, fragmentary pieces. "Smithereens," first appearing in English in 1829 as "smiddereens," is likely derived from the Irish word "smidirín" or "smidiríní," meaning "fragment." The demolition crew brought in the wrecking ball, which smashed the house to smithereens in a matter of hours.
