A scratching technique used to satisfy an itch on a scrotum. Nuts, unlike elbows, are carried by something called the nut
sack. The nut
sack is not a smooth surfaced piece of
skin like the back or
leg. It is actually skin with high elasticity which is often times folded back on itself and sort of scrunched up, especially while wearing clothes and sitting. A roller is performed with
one hand, even with pants on, using thumb and forefinger, griping the nut
sack in the general area of the itch, and rolling the pinched area back and forth until the itch is gone. The technique is not exactly a superbly accurate surgical operation but it gets the job done. Crude, maybe, but effective.
(Thinking to myself at
work) "I really need to scratch my nuts but I
don't want anyone to see me reach into my pants. I'd
better use the roller under my desk."
