Milk Up (poker)
1) Shuffle the deck by pulling out top and bottom cards
simultaneously, and forming a pile with these cards as they
are drawn, for the purpose of thoroughly mixing the cards
prior to shuffling.
2) Perform a cheating maneuver in which the cards are mixed
by an overhand shuffle, or something that looks like a casual
sifting through of the discards, in such a way as set up two
or more hands to be later dealt to pre-designated positions.
This is a cheating maneuver usually done by a mechanic prior
to some other move, such as hopping the cut and then dealing
bottoms.
