Steve! is a running gag from Video Games Awesome created by co-star Deacon Publicover. During the final Four Swords Adventures episode, Deacon claimed that the sound that lasers make sounded like they were saying "Steve!". Fraser listened, and berated Deacon because they sounded nothing like that. Deacon and Fraser eventually appointed "Steve!" as Deacon's catchphrase to say when trolling, and even Becky and Ben admitted the laser sounded like Steve at the end of the playthrough.
In later shows, like Pre-PAX Prime 2012 Show and Trailer, the Live Pax show, and the Post Pax Show and Trailer, Deacon can be heard saying Steve to the camera as a novelty. Some people also refer to a Steve as a person rather than a sound effect.
