Ghost gum is the much-tastier form of of marshmallows that you can make when pulling 1 or more big marshmallow between your forefingers and thumbs until it turns to delicious, stringy white goo. Similar to, but better than, Fluff.
I was going to roast marshmallows, but I made ghost gum instead, it was way better.

A gum wraper that appears to have gum in it, but when you open it there is nothing there.
Damn, my breath is rank, and all I got is ghost gum.
