Clap-In
From IRC Improv Wiki
The "clap in" form is one of the signature forms of Empty Stage Comedy:
- A group of players stands on the back wall of the stage while a scene is playing
- At an appropriate point a player will clap their hands loudly
- The plays already on stage will freeze
- The player that clapped will join the stage, doing the following:
- Bring in others they want to join scene
- Tagout those that they want to leave the stage
