Galavauntieing
A galavanter who's so determined to be your auntie that she'll even try to be your auntie by eating your favorite snack, even if it's the last one.
My cousin ate my last bag of chips just to be my auntie. I had to eat cereal for a week.
My neighbor ate my pizza just to be my auntie. I had to eat a sandwich.
My brother ate my ice cream just to be my auntie. I still hate him.
