J-Virus
J-Syndrome is when someone disappears for hours with a stupid excuse and then shows up acting like they were never missing, even though they were the one who messed up the plans.
Said they had to 'do laundry' and left the group hangout, then showed up 4 hours later to eat the last slice of cake.
Told everyone they were 'meeting friends' and vanished, only to come back to say they missed the best part of the event.
Left the hangout to 'get a drink' and came back to ask why no one told them about the secret surprise.
