NPC-Vibe
Nonplayer characters are a concept that most video game fans are familiar with; filler in a scene, though they may have a part in the script, not primary or even secondary; they are a background fabrication. They don't usually have defined roles or characters, the equivalency of a cardboard cut-out video image. The Nonplayer character vibe is when somebody puts off a feeling reminiscent of the empty, soulless vacuum of a nonplayer character.
