partying

If you're talking about the sixteen main sororities, they all party. But if you're trying to steer clear of hard partying, I'd go to Chi O, Alpha Chi, maybe Alpha Gam, AOII, DG, ADPi, Gamma Phi, Phi Mu, and maybe Theta. KD, Kappa, Alpha Phi, DZ, Pi Phi, Tri-Delt, and Zeta all have girls that party way too hard sometimes.

I'd say your best bet is AOII, ADII, and Alpha Gam. Never met a single one at a party. Everyone else parties pretty frequently. DZ, DG, Kappa, KD and Tri Delt all party a LOT. but Alpha Phi is definitely the biggest party sorority, nothing wrong with that but if you're not much of a partier, then you won't really fit in with APhi.

I'd say ZTA, KKG, DDD, and APhi party more than normal.

ADPi or AOII. Both are known for being boring. If you're not down for partying i'd steer clear of Kappa, Tri delt, DG, KD, DZ, and APhi

Some of the ones listed aren't that accurate. It's hard to say which sororities are or are not partiers as a whole, since there about 300 girls in each sorority, but here's a brief breakdown. I think most people involved in UAs greek system would agree

Wild girls of old row: KD and KKG (pretty hard to tell them apart when at a bar or party actually)
Wild girls of new row: Alpha Phi

All houses have parties girls, I mean these are social organizations.
Here are the ones with a rep/not a rep for partying. Not necessarily fun/not fun though.
