To fish 

To pay attention to other people's conversation, either because it concerns you or just because you're nosy.

Example 1:

A: Lisa is always fishing...
B: Is she? I never noticed it.
Lisa: That's because I'm discreet.

Example 2:

A: The secret to fish without being busted is to use your ears, not your eyes.
