Sorry, I really should have explained better.
"Pot odds" is how much money your opponent is getting in relation to the pot size. For example, if you are betting $100 into a $500 pot (thus making the pot $600), then your opponent is getting odds of 6:1 to call (he calls $100 to win the $600 that is in the pot at that point -- so he can win six times as much as he puts in). The odds of hitting a flush or a straight are 4:1 against, so if he's drawing to a flush or straight, you want to make sure the odds he's getting are lower than 4:1. Often, you just have a pair and can easily lose to hands like two pair or three-of-a-kind as well... so, basically, the idea is to make the opponent pay if he's going to draw a card to beat you.
On the other hand, if you think he will lose even if he makes his straight or flush (e.g. you have a full house), by all means let him try to hit it if you don't think he'd pay you off otherwise. Poker's all about making sure your opponent is on the wrong side of the odds.
