A catholic, usually a woman, who in addition to being a devout catholic, believes in some combination of faeries, ghosts, ley lines, unicorns, crystal vibrations and certain other new agey stuff that might otherwise make someone think she's into wicca. These women tend to collect lots of crystals, and or figurines/statuettes. Purple and pastels are popular in this croud.
I ran into my high school girlfriend. Yeah, the one who used to believe in witchcraft and shit. Yeah, she calls herself a traditionalist catholic now, but she's really into unicorns. I guess she became a CRYSTAL CATHOLIC.
