A non-scientific measure of the level of staleness of a food item. Usually used when referring to stale candies such as
sour keys and wine gums.
The test is comprised of wiggling (or squeezing if it is too
small to be effectively wiggled) the item between the thumb and the forefinger and observing its stiffness relative to it'
s stiffness in its fresh state. The greater the deviation in this comparison, the greater it's degree of stalinity.
