Refreshman 

Similar to a supersenior, but a refreshman takes first year classes, then changes majors putting them in freshman courses again for what should be their sophomore year.

Guy 1: dude, it's you're third semester, what are you doing in speech101?
Guy 2: I changed majors, so now I'm back to first year classes.
Guy 1: dude, you're such a refreshman.
