jail gum 

One of many creative innovations that can be found amongst inmates in juvenile detention. Made by applying small dabs of toothpaste on each corner of a square of toilet paper, then folding the square into a smaller and more condensed version of itself, and finally dampening it with water. It has vaguely similar properties of real chewing gum and the toothpaste adds a rather cheap taste of mint.

I tried some of this stuff and laughed my ass off as to why someone would ever want to make this.
