which frats and srats mix?

Because there were no socials last year, it’s kinda hard to say, but I’ll try my best to give you a good estimate.
Aphi and gphi almost exclusively mix with each other. Aphi likes phi delt, gphi loves adp. Sig chi wasnt on campus long enough to really assign them to a sorority, and aepi goes between aphi and gphi. Theta doesn’t really have a frat, and they’re sort of known for their poor relations with both frats and sororities. But that could easily change this coming year. A lot of frats have beef with phi delt, but other than that you can find the frats throwing joint parties all the time.
Dz and axo are pretty close to my understanding. Dz is often seen with akl, and axo was with fiji before they got kicked off, so I don’t know who will fill their spot. Aephi and tke are inseparable. I’m not totally sure where pikapp goes, but I know sig ep can often be with theta.
Aoii and alpha sig definitely go together, and same with beta and pi phi. Dtd and sammy are tbd, I’m not sure I’ve ever heard these guys having a social.

it’s generally based on “tier”, and frats/sororities will mix with others in their tier.

aepi mixes with aphi and gphi, and partially theta although the above comment got it right that theta is in a weird place.

Theta’s strongest connection was ZBT, but since ZBT has been gone they haven’t really found a replacement frat.

phi delt and ADP also mix with the other top sororities but none specifically more than any others. They also have beef

sigma chi gets whatever it can

aephi and tke are inseparable, probably the strongest relations of any on campus.

AXO and DZ are mixing with many frats, but none super closely. that’s generally the vibe for mid tier sororities.

aoii and pi kapp have been closer recently than before. aoii also mixes occasionally with alpha sig and sig ep, and since sig ep is huge in membership they are guaranteed to have scattered relationships.

pi phi and beta have always mixed

The above 2 comments are good, but i’m gonna do a 1 to 1 pairing for simplicity. Based on the past 2 years (after FIJI and ZBT were gone). These are all generalizations so don’t get butthurt.

ΑΕΠ + ΑΦ
ΑΔΦ + ΓΦΒ
ΦΔΘ + ΚΑΘ
ΑΚΛ + ΑΧΩ
ΠΚΦ + ΑΟΠ
ΤΚΕ + ΑΕΦ
ΒΘΠ + ΠΒΦ

I left out ΔΖ for sororities since they don’t really have a 1 to 1 counterpart. The same goes for the mid/bottom frats I left out, ΑΣΦ, ΔΤΔ, ΣΑΜ, and ΣΦΕ. These guys don’t have one matchup but they mix with some sororities here and there.

ΣΧ is weird to categorize. Some of their brothers date top girls, others mid, others bottom. It’s hard to say where they’re at now with no mixers recently. They definitely mix more top than mid or bottom, tho.
