South ( poker )

Go south.
1) Remove chips surreptitiously from the table (so called because on a map that's the direction they go), or pocket winnings while playing. Also called rat hole.
2) Palm or otherwise surreptitiously remove cards from the deck for later introduction (by a thief) at an opportune moment.
3) Leave a game or card room with money obtained dishonestly.
4) Disappear. "I lent him $20 and he went south with it."
