I am an ex-ADPi. If you want to freak them out-here’s something from their ritual:
The Password to get into meetings is “adelphae” pronounced “uh-dell-fay.” It means sisterhood. The handshake involves a regular handshake with your forefinger and middle finger extended out and pressing against the other person’s wrist.
There are two degrees of initiation, the blue degree and the white degree. The white degree is first – it’s where the history of our ritual and symbols are revealed. There are two stars on our badge, the star of truth and the star of hope. The third star is revealed in the initiation and everyone kneels and points and says “lo the star” and then the pledge is blindfolded again. Then you are taken into a room where you read little notes people have written you and stuff and then they come get you again and put a blue collar on you (you wear a white robe). Then you go back and other stuff is said and you take vows. You, your big sister and the president and the treasurer all take a drink of water out of a shot glass and say “I pledge my self and blood of my sisters and of myself to keep this covenant.” You then get pinned with your big sister’s badge and you wear hers until you get yours.
Spread the word. Enjoy.
