When you win a race or a game before another person, you beat them to the finish line. You win.Originally Posted by whl626
When you tell a joke, the last words of the joke are called the punch-line. For example,
What did one wall say to the other wall?
Punch-line: I'll meet you in the corner.
To beat someone to the punch-line, means to say something before someone else has a chance to say it.
All the best,
