Any form of transportation, which due to it's poor condition, rattling, and vibration, causes a womans mammories to jiggle something fierce, providing extreme sexual gratification to the driver.

2.that booty call last night asked me if i wanted to have JiggerNuts, i said yes, then she tasered my nut sack.
