In American English, Holy Rollers refers generically to Pentecostal Christian churchgoers including shakers, quakers, and pentecostalists. It can also refer to the former methodists.
The term is sometimes used derisively, by those who do not understand spiritual experience.
It comes from the effects that some forms of spiritual experience have on the person themselves as they fall down unable to support themselves any longer. Once spiritual experience takes hold many people go catatonic or atonic in a trance state and as a consequence fall down and may roll about on the floor.
Gospel singer Andrae Crouch has stated, "They call us holy rollers, and what they say is true. But if they knew what we were rollin' about, they'd be rollin' too."
