Heckling is when an audience member shouts out during your set without permission. Whether it's good or bad, it ruins your flow, and it can even ruin a punchline. One you've spent months perfecting. When you're loose, it breeds interaction from the audience if they don't understand you've been perfecting this "conversation" for months. Heckling is the pits! If you're the comic, that stage time is YOUR time. We had to send Ellis to therapy because he has some untreated trauma from past heckling experiences. Don't be THAT audience member. As a comic, you have control to ignore it, engage, shut it down, or anything in between.
Heckling is just talking when you don’t need to be talking.
