I don't know which sorority you are, which would help some- but one of our chapters of AGD had something like
" We choose to develop friendships with these chosen few" which is kind of a take off of one of our lines. Doing something like that is cool.
If you are looking for an overall skit idea or theme for rush, luaus are always popular (although OTW may not think so!
Uhm, another one may be something like Hee Haw (ADPi here does that!) Another one AOPi does is AOPi TV we also have Alpha Grammies!
If I can think of anything else I will let you know. If you want to PM me I can tell you what I know other sororities do!
