The phrase originally referred to a preacher of a type still familiar: one who does so in an aggressive way and who bangs on the pulpit to give emphasis. At the time the expression was first recorded — in the Cromwellian period of English history, roughly the 1650s — the allusion was to nonconformist preachers.
