To win a pot with a hand that would have folded to any bet. For example, two players enter a pot of draw poker, both drawing to flushes. Both miss, and cheque after the draw. The player with the ace-high draw "backs into" winning the pot against the player with only a king-high draw. Also to make a backdoor draw, for example, a player who starts a hand with three of a kind, but makes a runner-runner flush, can be said to back into the flush.
