acronym, it stands for "intellectual jewish stoner", and refers to any guy who fits that general description - they general enjoy jam bands and/or jazz, really good books, weed, and birkenstocks. many have jewfros, and play in a band. they're usually rather politically liberal, and from one of the coasts, though they are most commonly found in the northeast.
