bible-thumping

The term is a vivid American English compound, first attested in the mid-20th century. It literally combines "Bible," the central religious text of Christianity, with "thumping," the act of striking something heavily, often to create a percussive sound for emphasis. The imagery evokes someone who forcefully and repeatedly "beats" others with the teachings of the Bible, much like a preacher might thump the pulpit for dramatic effect during a sermon. This metaphorical extension captures the perceived aggressive, uncompromising, and loudly demonstrative style of proselytizing associated with the term, transforming a physical action into a descriptor for zealous religious behavior.
