Gaff- is this what Rick Reilly wrote an article on a couple weeks ago? The pouch that can be drained of its beer via your zipper?

Almost better than the stadium pal, which allows for 0 bathroom breaks until your pouch is full! As Reilly put it, invented by Bengals fans (what are they going to miss, a punt?)
