What driver or passenger of a car uses when he/she fails to get one of the few precious cupholders in a car, and is forced to put the ice cold drink between their legs, usually just below the crotch region.
Aww Man! i have to use my crotch pocket to hold on to my drink because my stupid Buick only has two cupholders for 5 people.
