magic darts

Most commonly used to say something hit the spot, actually as a reference to the item, ie: if you wanted to say "My plan solved all the issues perfectly", you could rephrase it as: 'Solved everything with my magic darts'



Origins:

Magic Darts actually has its origins in the traditional geek community, the geeks that play Dungeons and Dragons (first published 1974), where mages had the ability to produce magic darts that would always hit their targets (assuming you rolled the dice well enough). As happens some geeks started to use the phrase outside of their groups and slowly it has been taken up by others



Generally the spells used within D&D have originated from myths and legends around the world, with Magic Darts debatedly coming from the ancient Finns (called Laplanders), who were believed at one time to be great magicians, they were said to launch lead darts, about a finger - length, against their enemies, believed to send (with the darts) grevious pains and maladies.



Note: Chances are that if you hear some use the phrase 'magic darts' they are (or at least were) a D&D playing geek, as it is still not in wide use.
