This is a bet used in soccer more than in American Football. If you’re not sure who is going to win a game, say between Real Madrid and Athletico Madrid, but you feel pretty confident that both teams are going to score at least one goal, you can make a wager on that.

If both teams do manage to score, again, for example, say the final score is Real Madrid 3, Athletico Madrid 1, then a bet on both teams to score would be a winner.
