so who hangs out with who?

I'm a incoming freshman this fall, and I'm curious if anyone could help me out with which fraternities hangout with which sororities? I have a few older friends in sororities and fraternities here who have given me the "rundown" but I understand that while they are each in different organizations here they can be very biased..

My girl friends are all obviously biased so I'll leave what they said out for the most part (all said they hang with KS, PKA, DTD pretty much in different orders) but my guy friends have generally said,

My friends in KS said they see PM KD and AOll mostly with a good amount of DPhiEs showing out too. They said they have some ZTA's and GPB's from time to time.

My friends in Pike said they see KD DPhiE and Phi Mu. GPB and AOll show out in good amounts too they said.

They also said these pairings.

PKP, KD GPB ZTA PM
OX, ZTA DPhiE
DTD, DPhiE GPB ZTA
KA, AOll PM
SN, AOll GPB

That's pretty much all they knew can anyone help? I want as much info as possible on this before I go into rush with an open mind. Just to see who I might be seeing before I become a sorority girl.
