Well I'm assuming meaning you are losing after flop. So say you are against 2d2h, and have 9s10s. With flop of 7s8s7c. You have a lot of outs lol. The 3 remaining 8's, the 3 9's, the 3 10's. That's 9, then the 9 remaining spades, that's 18. The 3 non spade 6's and 3 J's, that's 24 outs , more than half the remaining cards.
