Get the Flip Cow Udders mug.
When you hang a bag of Franzia from a basement ceiling or from any apparatus that is above your head. Thus allowing you to open the valve and suckle the teet of the bag of franzia or the "cow udder" at mouth level. One must proceed to finish the bag by himself or with friends.
Max: Hey Dan I bet you and I can do a whole cow udder by ourselves.

Dan: Let me hang that shit up man!

2 hours later..... or maybe 1 hour later...

Max & Dan: What the fuck happened!?!?!? Fuck it clown!
