People who are very passionate about their score do whats called "plug pullin". It basically means what is said. By pulling the computer plug out of the outlet you supposedly disco.
Although I dont have a very intimate knowledge of computers i do know that they run off powers supplies that makes this theory irrellevent. Even if you pulled the plug on your PC, it would still have power for a good 2 to 3 seconds on most systems.
However if your running a laptop with no battery installed then this would definitely work if you removed the plug upon encountering danger.
A bich move if ya ask me.
Nobody else going to step in and mention that this would probably quickly destroy the internals of a computer?
The term "cable pulling" comes from yanking the internet connection, not the power. In any case, it doesn't happen all that often...I'd be surprised at more than five times a month. Though in these ones where the person just vanishes it's probable. The situations where someone, say, flies through a mountain, whips on your six, then kills you is
not some guy yanking his cable, coming around, then plugging it back in like people love to believe. Networks just don't work that way.
ImADot's explanation is the most common cause.
