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. The typhoon's gale-force winds have been smashing the village to smithereens over the last few days.
smash the teapot
To resume drinking alcohol after a time of sobriety. The "teapot" here is likely a reference to the term "teetotaler"—one who does not drink alcohol. A: "But Paul's been sober for years. Has he really smashed the teapot?" B: "Yes! I saw him drunkenly stumbling out of the pub last night."
