Nashville Skinny Someone who has become skinny not by choice, but rather because they have eaten very little over the duration of several days. This could be due to a lack of communication or little access to real food. The idea of food is enough to make you full.
The term originated at a fraternity formal in Nashville. Said female-date only consumed a donut, orange juice and peanut m&m's over the course of 3 days and was able to survive. The lack in nutrition led her to be "Nashville Skinny" as a result.
My stomach seems to have grown a bit after eating that quesadilla, I think I'm losing my Nashville Skinny.
