(A.k.a. "the blue screen of death" or "WinNuke") Technique for causing the Windows operating system of someone you are communicating with to crash or suddenly terminate. The "blue bomb" contains information that the operating system can't process. This condition causes the operating system to "crash" or terminate prematurely. Its name comes from the effect it sometimes causes on the display as the operating system is terminating - a white-on-blue error screen.
