Usually someone who picks and chooses different verses from the Bible, to fit their political gain. Most of the time being hypocritical and not going by the Bible themselves. Not true believers of the bible, but using it in a way to control the narrative.
"Trump is such a bible bunny, for selling Bibles to fund his campaign."
"The legislators pretending to speak in tongues on the Senate floor, are such bible bunnies."
"Westboro Baptist church is really out here trying to kill people, instead of save them. What bible bunnies"
