I've heard that one too. But the last thing you want to do to become a fratenity's sweetheart is sleep with them. I have been a Sigma Chi sweetheart nominee the past couple of years and they actually look down on the girls sleeping around just for a nod or a chance to win. If you do have to sleep with them to win I wouldn't want to be that fraternity's sweetheart, I mean what does that say about the members of that chapter!
