Trench, The
The Trench is Sidespeak for Earth. Earth is primarily populated by 1Ls and Earthbounds. When a Sider has an assignment from the Big Guy, it usually involves a trip to The Trench.
Trenchmite
Trenchmites are the denizens of Earth. While the majority are First Lifers, there are millions of Earthbounds (earthbound spirits and souls). The people on StevesBigList really hate it when we call 'em Trenchmites.
Uptown
Uptown is Heaven as it has been idealized for several millenia. You know the tale, puffy clouds, white robes, golden streets, and a Cubs team that actually wins the world series. There is also no country music Uptown... except for Johnny Cash. The Big Guy loves Johnny Cash.
