When an asian woman/girl only goes after brown dudes (do not necessarily have to be mid but it is likely). They'll typically be really good looking girls as well.
(Note: unlike Oxford Study, Princeton Study doesn't have an actual study for this, it is merely used for its name since how common this occurence is and because Princeton has a pretty high south asian population)
Me: damn that ABG is a baddie
Bro: lucky for you, she mainly goes for brown dudes
Me: ayyy this is why I love Princeton Study
