To the best of my knowledge BGLO's call their fellow sisters - sorors and GLO's call their fellow sisters - sisters...

Furthermore I admit when I think poorly of a house I refer to them as "frat boys" but when I respect a house I refer to them as "fraternity men". everyone knows the degrading saying of sorority girls "I will not date a frat boy". but I add to it "I will not date a frat boy only fraternity men."
