Aaliyah

the over-achieving female student in your school.

Example:
Guy: Why do you look so stressed?
Girl: I'm writing a chemistry test next period and I only went over the whole textbook 42 times. I'm scared I might fail.
Guy: Geez, you're such an Aaliyah.

Aaliyahism

Aaliyahism
The irrational disappointment of achievements just shy of perfection.

Example:
Teacher: Why is your test not signed!
Student: My mother refused to. She was disappointed that I only got 98,5%.
Teacher: Is she suffering from aaliyahism.
Student: I know right!
