houses

you're just asking for too much here.

1) the rankings are posted all over this website
2) there's no real way to generalize who a house hangs with cuz all the different PC's hang out with different houses
3) the reputations are also posted here somewhere

sig chi du sigep ksig sae hang out with top and middle sororities (kappa gphi dg axo piphi aphi)
theta chi fiji hang out with less top and more middle
lower tier frats tend to hang out with lower tier sororities (tridelt theta)
aepi and sammy hang out with chio aephi and sdt

Alright, just to lay things out,
You can find any girl from any top tier sorority at any Ksig, SAE, Sig Chi, DU and Sig ep party. There are also girls from every single sorority at most of these parties

Both FIJI and Theta Chi have girls from top tier sororities at their parties, however, most the girls at the parties are from upper middle/middle sororities (APhi, AXO, PiPhi)

You would not find any girls in Kappa Gphi or DG at a lodge, pike or chi phi party. For these parties, there are some middle tier girls but most of the girls are the parties are theta or tridelt.

That's a bit over simplified, but that's kinda the gist of things
