Any idea what movie this is?

[AOII*Azra-elle]

Hey y'all I'm hoping someone could help me out. I'm looking for an old 80's movie and I'm not sure of the name. In the movie the guys try to 'initiate' the freshmen and run around during the whole movie trying to paddle the guys and the girls get ketchup and mustard and food all over them by the upper class girls. Can anyone tell me who is in this or if they know the name of the movie? That would be great!
