A variation of the name of the new Micro$oft OS: Vista
It is:

1) A representation of how truly annoying and frustrating Windows Vista really is
2) The stream of swearing that comes from someone when Vista crashes
1)
Person one - So... you got a new PC... what are the specs?
Person two - 4GB RAM, 500GB Hard disk Windows Vista
Person one - Noooooooooo! NOT VISTAAARGH!

2)
Person one - I tried playing Solitaire on my laptop again
Person two - Wait you're running Vista, right?
Person one - Yep:)
Person two - Bet it crashed, didn't it?
Person one - Yep:(
