Dwaine - it sounds more like something someone made up because "gnarat lublub" was hard to pronounce.

Actually, I've seen a couple of different instruments using that name in "street jams" at Winfield, but the few examples seemed to be different (from each other); and I didn't have a chance to discuss them with the operators. The ones I saw appeared maybe to be homebuilts. It would be interesting to know if there's a "tradition" for an instrument by that name.

(It should be noted that in many of the "street jams" at Winfield, verbal coherence is not a requirement.)
