Being pwned by any Windows operating system.
This is used to describe what happens when playing a graphic intensive game online and user is crushing all the other opponents. Then out of nowhere his/her computer crashes to the Blue Screen Of Death BSOD and player is disconnected from the server and loses miserably.

Winpwned can be synonymously used with BSOD
