Whiskey Grandma 

Whiskey Grandmas are the older variant of the Wine Mom and Vodka Aunt. Where as Wine Moms are classy and Vodka Aunt's are rowdy, Whiskey Grandma's tend to spend most of their time being bitter from age. They are more inclined to avoid social situations to "watch their stories" and drink alone. They are very obscene and crude, but are still respected and revered due to their ages of wisdom and deep love whenever they show it. They have built up such a high alcohol tolerance that you will rarely see them even stumble after a night out drinking.

Grace has become such a Whiskey Grandma recently
