Silver bullet has slipped into
warez d00dz speak as meaning the one
right thing to solve a specific problem.
A (poor) example:
"The only silver bullet for playing copied Playstation games is a mod chip."
Also hodgepodge Coors Light is The Silver Bullet, and yes it is disgusting. Coors comes in an off-yellow color can, and for (and in) equally bad taste is called the Golden Shower.
