Extrapolate!

This is extremely random, but I came across this post today, and loved this tangent:
My friends and I have a running joke when we're watching sports or playing video games. If our team takes an early lead someone will yell "extrapolate" meaning let's just end the game now and generate the final numbers based on what's been played so far.  Usually it means a final score of something like 1730 to 0.
I wonder if everyone has played this little game at one time or another, without really giving it a name.  I suspect so.  Now that I know what to call it, I think I'll play more often.
