An old person at the grocery store that if you have the misfortune of getting behind in the checkout line will make you turn from a soft, cuddly, loving person into a raging menace, because they still pay with a check meaning you probably will not eat your food till after midnight.
Person 1: "Dude what took so long with the munchies it's like 2 in the morning?"
Person 2: "Sorry man I got stuck behind this old Cotton-topped grocery gremlin at the store."
Person 1: "Wow sorry man, here sit down, let me get you a strong drink."
