The strong, mysterious feeling of anxiety while attending school. You can't quite put your finger on it, but it ALWAYS comes around when you're at school, and is replaced with extreme boredom when summer break comes around... it's school's way of saying, "Ha! You're fucked now!"
"Ugh... why do I feel so sick? Must have a terrible case of schoolitis."
