Great question! Well, according to Wikipedia, Improvisational theatre, often called improv or impro, is a form of theater where most or all of what is performed is created at the moment it is performed. In its purest form, the dialogue, action, story, and characters are created collaboratively by the players as the improvisation unfolds in present time, without use of an already prepared, written script.
