(verb.) When something totally blows up, both literally and figuratively. Thus, can be used to express either the utter failure of something (eg. exam, weekend spent with your new boy/girlfriend, etc.) or when something is destroyed in a very spectacular manner (eg. a star, someone's dignity, etc.)
Were used in the episode of Futurama called 'The Day The Earth Stood Stupid'
The Brain Spawn (dreadful menace of the space-floating brains) are about to destroy the next planet in the lane - the Earth:

Fry: This planet is next in line.
Leela: That's Earth.
Fry: stares cluelessly
Leela: The planet we live on?
