dirty rushing

Anyone else notice how AXiD and Phi Mu were the only ones not dirty rushing at the tailgate? (at least the only ones I didn’t see doing it....) GSU says they have strict no dirty rushing rules but it seems not many of the sororities here follow it... kinda makes me not wanna go through recruitment anymore if I’m gonna be compared against all these girls who already I’m sure have bid promises to sororities... any advice?
