What does the term "visiting underdog" mean in the world of sports betting? What is the definition of the term "visiting underdog"?

In sports betting, a "visiting underdog" means that a team is two things:

1) Away from home
2) Underdogs to win (meaning, the other team is the favourite)

Let's look at an example - let's say that the Cincinnati Bengals are travelling to play the Denver Broncos on Monday Night Football.

Here are the odds:

Cincinnati Bengals, +11, -110
Denver Broncos, -11, -110

According to these odds, the Bengals are the "visiting underdogs", as they will be playing away from home AND be underdogs to win.

The straight up odds for the game might look something like this:

Cincinnati Bengals, +340
Denver Broncos, -400

So, according to these odds, a successful $100 wager on the Bengals would yield a total profit of $340, while a successful $400 wager on the Broncos would return a total profit of $100.

As you can see by this odds, the Bengals are the "visiting underdogs".
