One who uses the Bible to attack/defame others' characters instead of as a guide to proper living. These people tend to be depressingly ignorant of anything else except the Bible and behavior as expected by the religious.
That Bible Thumper makes me so sick! Every day, he stands on my porch shouting about how I'm doomed to a flaming eternity in Hell just because I watch Crank Yankers and South Park!

Originating from typically southern US fundamentalist Christian sects given to evangelizing in a very outgoing, rumbunctious way, often characterized by a religious bigot standing on a street corner, with or without foam around his mouth, shouting about how we should all turn to Christ, whilst vigourously thumping his soft covered bible for emphasis.
Their actions usually do more harm than good to their cause and bring into disrepute and ridicule those more reticent Christians.
He's a bible thumper, so don't go near him.
He thinks everything in the bible should be taken literally; he's a foolish bible thumper.

The cause of many major wars, genocides, and crimes against humanity during the last 20 centuries.

Some ass clown who tries to convert people to his version of Christianity, using a book he's too ignorant and incompetent to fully comprehend. Fully ignorant of the historical, cultural and literary context of the Bible. Every Bible thumper gives the South a bad name. We're not all like that down here, promise y'all that.
The Bible thumper told me I was going to Hell, so I gave him my rosary and told him to pray for me.

two definitions:

1) Someone who is extremely evangelical in their religious belief. Many of them believe that their denomination is the one true denomination, and all others are wrong or evil. They try to make you feel like your life is a waste and use scriptures that have nothing to do with what they're saying to "explain" themselves.

2) Someone who screws with a very religious person.
Dude 1: "dude, freaking bible thumpers don't know what they're talking about!"

Dude 2: "dude, you are a bible thumper! Didn't you get with that devout christian girl?
