Nubrub Edit Meaning

1.

When stuck in a crowded, shoulder-to-shoulder, situation (ie. elevator, concert, Disneyland queue, etc.), you pull your arm inside your short-sleeved shirt and then stick only your exposed elbow through the sleeve. You then proceed to nonchalantly rub your stump on the uncomfortable stranger standing next to you.

While traveling in a crowded elevator in the Sears Tower to the observation deck, Larry proceeded to nubrub at least 4 people much to the delight of his giggling son.
