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 ;)
"see that fine ass lady right there? she's a phi sigma sigma."

a bunch of really pretty chicks that like to have a good time. they get crazy and know how party, at my school (j&w) there sorority of the year and always win greek week. they always have the most girls that wanna rush their sorority - no wonder why. they attract the hot new freshman because of their good looks, popularity and clothes. they get things handed to them because of who they are and think their better than everyone else, even though it is true.
student 1: we have a 2 absence rule and this is her 4th absence so far! why hasnt she been dropped from the class?
student 2: shes a phi sigma sigma , and shes hot
