a) Officially: a society of collegiate women brought together by the common passion of philanthropy. The organization aims to work towards substantial philanthropic goals through events, fundraisers, and related endeavors. Similar to a Greek organization.

b) Unofficially:
1) the front for a bunch of girls who can't accept that their chapter of Kappa Alpha Theta was thrown off campus because of their extreme hazing. Basically, an attempt to make a loophole so they don't get in trouble for having mixers.

2) evidence of the same girls' stupidity, considering that everyone knows it's false, but they still insist on pushing it and handing their roster to the administration.
A: I'd love to join a sorority, but I'm really only concerned about the philanthropy part.
B: You should join Sorella! They only do philanthropy!

A: What's that big group of girls over there?
B: Theta's dirty rush- I mean, a Sorella social meet-and-greet.

A: Did you hear Sorella got denied university recognition again?
B: Will they ever learn?

Get the Sorella mug.
2 girls refered to as CC and PP, brought together 20 years into their lives to find out that they are identicle. Both full blown guidettes and go around with attitude. Can do a nasty fist pump and can do it with style. Both have some hate towards a bridge that seperates the both of them. Always got shit to say but have huge hearts. Both goodlooking and stops every guy in their tracks. Will speak italian to curse off any fucker, or "foker" they see. One now talks more Ny, and the other is turning into a Jersey Girl. No distance will seperate these 2 and one will not sleep knowing that the other one cant. They love button downs and the smell of aqua di gio. if your goodlooking and walk up to them, expect a scream of "waawaa!"
La sorella's: from a different life brought together in this one to raise hell.. goodluck boys,better be brothers cause these 2 want the same last name.

Get the La Sorella's mug.
Sister of extraordinary character, grace, peace and love. Steadfast encourager and dearest of dears. Unsurpassed in hand-holding, giggling, 'there-thering', 'Oh, now you've got me crying,' and just plain old down to earth sistering.
I was having a horrible day, but Veronica d' Sorella made me feel that no matter how bad things were, it would be okay.

and...

It would have been the worst three years of my life but for the care of Veronica d' Sorella.
