badger to death: o que isso significa?

Imagine you know something your friend wants to know, but you can't tell him because it's a secret. The problem is that he keeps insisting on you telling him in such an annoying way you can't bear anymore. So a third friend comes along and tells you: If you don't tell him, he'll badger you to death until he finds out. When someone badgers somebody to death, they annoy them very much. So your friend is annoying you so much you end up giving away the secret. That's all for now. Take care!
