A term used to describe art that is funky weird or unusual, usually sort of primitive and that doesn't come from the snooty art scene, but from just plain old folks. It can be disturbing, funny or just sweet. Folk art of the urban experience.
I keyed in "Outsider Art" on ebay and I found a bunch of wall sculptures by this chick that used plastic toys nailed to crosses! I bought the Xena one.
