The act of getting beaten and generally demoralized by a University of Purdue sports team (especially during March Madness)
Drunk Purdue fan to non-Purdue fan: Dude, your team better start scoring some points or they're gonna get purduped!!! YEEEEEAH!!!!

Hungover Purdue fan to another hungover Purdue fan: Hey, wasn't that awesome last night when we purduped Indiana!
