Someone who is a Christian, usually a Protestant, who is so ridiculously into their beliefs that they become super obnoxious about it. Will not tolerate any deviation from their beliefs, even from more moderate Christians. Feels the need to be really in-your-face about their beliefs. Extremely obsessed with proselytizing people from other faiths and other denominations of Christendom.
Man that guy is so annoying. He will not leave me alone about how much he loves Jesus and why I should accept him as my Savior, even though as a Catholic I already do. What a Jesus Nazi.
