a national sorority of only the best ladies. their motto is aim high, which they do in each and every aspect whether it's greek life, partying like rockstars, their GPAs, or any other spectacular thing that these phi sexy sexy's can do! they party with the best and can drink your boyfriend under the table. despite their rockstar partying status, they also manage to have the highest GPAs on campus, look fantastic all the time, give back to their communities and are great examples for greeks everywhere! may she's born with it, or maybe she's a phi sigma sigma ;)
