Definitely the "chill" house of the 3 top tier houses. They don't have the stuck up or trashy reputation of other houses. Hot for sure but also the nicest and most diverse of the top 3. These are the girls you want to wife.
very good friends with these girls and we hangout and party with them all the time. My house loves pi phi and it should be made very clear that they absolutely do not haze. its all a bunch of rumors. we would not associate with girls who do the stuff that is being said. these are the most down to earth girls on campus.
