Sklansky Bucks 
Edit
Sklansky bucks/dollars are theoretical money won or lost based on the Fundamental Theorem of Poker. The FTOP is discussed in The Theory of Poker.
Basically, if you lose a hand but your opponent made mistakes, such as drawing to a flush without proper pot odds, you may lose the pot but you have earned Sklansky bucks by causing your opponent to make a mistake.
