We call them Pi Chi's and I just returned to my chapter after 6 long months of Pi Chi training, recruitment and orientations. We do reveal a little differently each year because the Pi Chis decide what they wanna do. This year we did a stroll to the middle of the quad then backed up into two lines. We then did a "soul train" type thing where each pair of Pi Chi twins would boogie out to the middle of the line (while the rest of the Pi chis squatted down) then take off their pan shirt, revealing their letters.SOOOO much fun
