An anxiety disorder characterized by extreme fear of running out of Natty Light at any event or gathering, but most notably way too early in the night.
Example #1:
Good god, last night as the party was gettin legit, and I was gettin balls deep in Liz, I suffered from a nattastrophobia attack. I shoved that cock juggling thunder cunt to the floor and ran to the fridge ass naked to find six fresh cases. I love my roommates.
