BSoD, or Blue Screen of Death, may refer either to a simple occurrence of an actual Blue Screen of Death, or to a trope named for such:
- Heroic BSoD: The darkest moment of the hero's story.
- Villainous BSoD: the villain version of the above.
- BSoD Song: The number in a musical where a character undergoes a BSoD of some sort.
...Or perhaps to the symptoms of a plot-significant computer failure caused by, say, a Logic Bomb.
