shamentarpen 

(noun, borrowed from German) a tarp deployed over a college football stadium to hide empty seats that would otherwise be seen by television cameras.

Baylor uses a shamentarpen to cover the fact that they can't get fans into the stadium, even when they have a Heisman winner at QB. Rice uses a shamentarpen over each end zone, but each of them covers a number of seats lower than the average Rice SAT.
