Auto-mail 

A type of prosthetic used in the Fullmetal Alchemist world, which is the best manga/anime to have ever existed. Could be just a replacement arm, or even a shotgun/machinegun/missile launcher for your leg. Maybe just a new finger? Who knows? It can replace any thing.

"Don't worry, get an auto-mail d@#$ to repace it!"

Automail 

Automail is a system of prosthetic limbs used in the Manga/Anime: Fullmetal Alchemist. The main character of the series, Edward Elric has two Automail limbs, as the result of an attempt to use alchemy to bring his mother back to life. The first person introduced in the series as an Automail mechanic, Winry Rockbell designed Edward's Automail. Edward often uses alchemy to transform his Automail into a weapon by making it sharp (much like a knife), he and Winry often get into arguments about his abuse of her mechanics.

Victor: John just lost his arm in Iraq.
Jack: Damn, Automail would work wonders right now...
