When I was initiated this spring, the chapter president of the collegiate chapter wore a white THONG underneath her attire, and she spent the entire ritual trying not to turn her backs to us so we wouldn't know it. The sisters who were standing behind her were turning BLUE from trying not to laugh. At one point she had no choice but to turn her side to us, so I got to see what she was wearing. I called her "Thongelina" for the rest of the day.
astroAPhi, I almost said "Oh ISHT" when I walked into the room, too!
