The usually unnecessary drama that takes place at conventions (cons). Usually caused by factors such as lack of sleep, long driving trips, carrying heavy luggage, cosplay malfunctions, seeing someone else with the same or better cosplay, malnutrition, hotel room and roommate issues, romantic breakups, betrayal that is taken personally, extreme heat, etc. Con drama is used commonly for facebook statuses.
Melvin went to Anime Boston cosplaying Riku from Kingdom Hearts. He saw someone else with a better Riku cosplay and then his friends kicked him out of the hotel room. I had to listen to his melodramatic con drama.
