After a long day, your sack begins to sag and slowly nestles its warm elasticity tween your legs. After an hour or two it begins to itch. So one must casually reach below and yank it up out of the crotch nest. This is the nutsack shuffle. Also known as a "nutty shuffle, plucking the birds nest and juggling"
Yo, I had to pull a nutsack shuffle in front of my girlfriend's parents at the dinner table. My hand came back w/ 3 curlys.
