Also known as "con-down". The feeling of sadness you get after a convention is over. What type of convention is irrelevant, as long as it is a group of like-minded people that you feel like you belong to.

Can also be used to describe the feeling of loneliness after having spent time with a partner, especially in a long distance relationship.
Person 1: Aww man, I wish that convention lasted longer...
Person 2: Dude, you have convention-down.

A school in Darjeeling, India. Known for its underqualified staff who act like it costs a shit ton of money to simply reply to a "hello". Very trauma inducing environment. All forms of patriarchal, misogynistic, anti-feminist views are enforced in this jail. All the mean girls here turn lesbian after 5th grade.
