Ghostcare

In Halo 2, when you're playing co-op. You and your teammate takes over a par of Ghosts, and the almost only thing your mate is doing is to smash his Ghost into fire and dust. No sence of care at all.

Dude 1: Stop smashin' in me! Man, your Ghostcare sucks!
Dude 2: Whaddya mean? *crash!*

ghostware 

Ghostware is a software that is rumored to exist, or will soon exist, but never does. It is occasionally used by companies to describe something that will be "the next big thing" in tech, only for them to "ghost" when it comes to actually deliver said product by a deadline (or many deadlines).
