look up any word, like bae:
 
1.
A student with a grade point average at or above a 4.0 that continuously does their schoolwork, pursues every extra credit opportunity possible, and pesters other students to bring their grades up. A Grade Nazi is often known to have a divine hatred of any grade they’ve received that is less than an A on their final report card. This might be because Hitler’s superior race was the Aryans race – which starts with “A”. Similar to the Grade Warrior and Grade Ninja.
Student 1 - "Dude, have you seen Ambrosia’s grades? She’s got 120% in her 5th hour alone!"

Student 2 - "Yeah, that’s because she’s a Grade Nazi. She complains to me about my average grades all the time."
