(noun) a teenage wiccan who thinks that Wicca is cool, but knows almost nothing about the religion aside from what she read in a few pop culture books on witchcraft--assuming she read them and didn't just make up a religion based on what she saw on television.
"Cassandra thinks she knows everything about witchcraft, but she's just a wicclet."
Acronym for Wiccan in Name Only. Someone who claims to be Wiccan, but seldom (if ever) observes the festival days or performs the appropriate rituals. Such people claim to know everything about Wicca, but in truth know very little about the religion or its practices.
"Cassandra claims that she observed the Samhain rituals, but I know for a fact she spent the night at a Halloween party.
She is such a WiNo."
