I had two nicknames as a Pledgemaster, only one of which I will share:
Big Brother "Vision of Excellence". . .I was PM the second semester of my senior year, during the same time that our Black Student Alliance was preparing its annual Visions of Excellence Awards Ball (for seniors who have made an impact on the community and university in a positive way). I actually received the award well after the pledges crossed, but one of them came up with the bright idea to call me "Vision of Excellence" anyway. Not very funny, but special nonetheless.
