A now defunct orientation event, during which new students are rounded up like sheep and put on South Lawn for various ice-breaking and orientation events. Students run around in the dark and are instructed to find people that had various things in common with them, such as birthdays, musical tastes, favorite ice cream flavors, etc. It was an extremely awkward event and has since been replaced with BlaZe. During the existence of CUnity, many students left en masse for other activities.
I have no idea what BlaZe stands for, but according to The Bwog, the orientation event included different events around campus, including hula hoop at the Business School, Sudoku at Barnard, Beirut (with soda) on the Barnard Lawn, and Word Games at Philosophy.
