Spend an evening around comedians and you will hear words that sound normal but mean something specific. Someone “killed”. Someone else “ate it”. There was a great “callback”. This glossary explains the vocabulary in plain English.
On the bill
- Host, MC or compère
- The person who runs the night: warms up the crowd, introduces each comedian and keeps the energy going between sets.
- Opener
- The first act after the host. Often a shorter set.
- Headliner
- The main act, usually last and with the longest set.
- Showcase
- A night with several comedians each doing a short set.
- Open mic
- A night where anyone can sign up to perform, often new comedians testing material. Cheap or free to watch, and unpredictable. It is where most comedians start; we wrote about how independent shows in Madrid get made.
The material
- Bit
- A short routine on one subject.
- Set
- A comedian’s full performance on the night.
- Tight five
- Five minutes of a comedian’s strongest, most polished material. The calling card for booking spots.
- Premise
- The idea or observation a joke is built on.
- Set-up and punchline
- The set-up creates an expectation. The punchline breaks it.
- Tag
- An extra punchline added after the first one, getting another laugh from the same set-up.
- Callback
- A reference to an earlier joke later in the set. Audiences love them because they feel like an inside joke you are now part of.
- Crowd work
- Talking with the audience and improvising jokes from the answers. Our article on the front row and crowd work explains more.

How it went
- Killed / destroyed / smashed it
- The set went brilliantly.
- Bombed / died / ate it
- The set went badly. Every comedian has done it, many times.
- The room
- The audience as a whole, and the mood in the venue. “A tough room” is a quiet crowd.
- Heckler
- An audience member who interrupts uninvited. Not the same as answering a comedian’s question.
- Getting the light
- A signal, often a torch from the back, telling the comedian their time is nearly up.
Formats
- Improv
- Comedy made up on the spot, often from audience suggestions.
- Sketch
- Short scripted scenes with characters.
- Roast
- Jokes aimed at a willing target, usually a fellow comedian.
- Live podcast
- A recorded or podcast-style conversation performed in front of an audience.
