PowerPoint karaoke, also known as PPT-oke, battledecks or battle decks, is an improvisational activity in which a participant must deliver a presentation based on a set of slides that they have never seen before. Its name is derived from Microsoft PowerPoint, a popular presentation software, and karaoke, an activity in which a performer sings along with a pre-recorded backing track (although there is usually no music or singing involved in PowerPoint karaoke).
