Wikipedia definitions of Fundie, Bible thumper, Holy Roller. All 3 of these words mean "deranged stupid asshole".

Fundie or fundy (plural fundies) is a pejorative slang abbreviation used to refer to religious fundamentalists of any religion or denomination, although it is primarily directed towards fundamentalist Christians.[1]

Bible thumper (also "Bible basher"; mainly US) Someone perceived as aggressively imposing their Christian beliefs upon others. The term derives from preachers thumping their hands down on the Bible, or thumping the Bible itself, to emphasize a point during a sermon. The term's target domain is broad and can often extend to anyone engaged in a public show of religion, fundamentalist or not. The term is most commonly used in English-speaking countries.[3]

Holy Roller (US) an enthusiastic Protestant prone to rolling on the floor, suffering from fits or "speaking in tongues" (Pentecostals during worship or prayer). The term holy roller, however, is applied to some Evangelical Protestants, especially charismatics, if they are vocal about their own religious views or critical of individuals who do not meet their moral standards. Similar to Bible thumper.[7]
