Folding equity is basically the chance that your opponent will fold a better hand.

Ex. If you have a lesser hand than your opponent, but there are three spades on the board, then you can bluff him off his better, but mediocre hand. The pot has $100 in it. Say your bet is $25, and you estimate there's a 50% chance he will fold. That means your folding equity is 50%, and this play is profitable, because you are paying $25 to win $50 on average.
