A female masshole. She may not necessarily be slutty, but will have non-sexual skanky qualities. Frequently blue collar, crass, and having the stereo-typical Boston accent. May have the I'm-hot-shit attitude with truck stop whore looks. Often projects an aura of whitetrash regardless educational or economic status.
