slower than the line out of hell 

An expression used to describe anything that is very, very slow. (since a line of people waiting to get out of Hell would logically not move at all!)

Cell phone call:
Guy: Hi, I'm going to be a bit late.
Girl: Why?
Guy: I'm at the grocery store and this line is slower than the line out of hell!
Girl: Well, get here when you can!
