text: A lot of people who answered your question have obviously not seen the movie, as this 'paddling' is hazing and not punishment.  Fraternities and Soriorities make paddles with their greek letters on them, and if they get caught using them their will be stiff consequences.  The way they are using them in the movie is not seen any longer, as far as I know.  My sister went through stuff similar to what the girls experienced.  Sports teams in high school may still do the paddle thing.  It is definately not a common practice.  We are not barbarians(any more)!!  :D
