Origin
disputed originFrom Cicero's Latin 'excitabat fluctus in simpulo' (he stirred up waves in a ladle); the English teacup form dates from the 19th century (Americans say 'tempest in a teapot').
They shouted at each other over a missing pen, but it was really just a storm in a teacup.
While the media predicted a major political crisis, the disagreement turned out to be a storm in a teacup that was forgotten within a week.
