Slang term used by upperclassmen at Boston College when referring to Upper Campus, where most of the freshmen live. Based on the Boston pronuncation of the word "upper", it is spoken aloud as initials (yoo-pee-ey).

Since the Upper Campus is entirely freshman dormitories, there is NO reason for upperclassmen to show their faces there, except to cradle rob. UPA frequenters might tell you that they were at "The Club", a late-night snack shack, but you can call their bluff by asking why they didn't just go to Addies, the late-night snack shack on Lower Campus.

     My little sister said she saw you last night on UPA.
     So what's her name?

               STEVE
     Who's name?

               PHIL
     The drunk freshman you hooked up with.

               STEVE
          (defensively)
     Shut up.  I was at "The Club".
