Are you challenging me to a walk-off?

What does walk-off mean in this sentence?

Thanks a lot.

I think this is a relatively recent addition to the language. It basically means a competition.
In America, they have competitions to see, for example, who can eat the most hamburgers in a certain length of time. This would be called an "eat-off".
So I assume in your sentence the speaker is asking if the other person is challenging them to a competition or a race in which they will both be walking.
