Kai-nanism
A bunch of people who act like Kai-Nan Lin is the most important person in the universe, and they make up weird names for themselves like Kai-Nanase. They spend all their time talking about him and nothing else.
'I would die for Kai-Nan Lin. I wouldn't even blink.'
'Kai-Nan Lin is the only reason I got through high school. I didn't even try.'
DM: 'If you don't like Kai-Nan, you're the worst person ever.'
