As said above its a scottish term meaning after 5 ie 5:00 - 5:15
This must be some kind of weird northern thing.
It's a Scottish phrase, as far as I'm aware.
This.As said above its a scottish term meaning after 5 ie 5:00 - 5:15
It really should be "bottom" of the hour, which would be 5:30 - 5:59. "Back" sounds dumb. Just like an inning in cricket, I would think. (edit: do they call it that?)
How can you add something and get lower?Definitely this. You can argue over whether it makes sense, but that's what it meansIt means just after the hour. So if you finished your work at 5pm and lived nearby you'd be home "at the back of 5".

Ahh, but if I'm taking the minutes away from those remaining in the hour, the stack will be getting lower.Well by most people's logic if you're adding minutes, you're stacking them and they're getting higher - so it'd be top of the hour ?How can you add something and get lower?
Like sands in the hourglass....This seems fitting, also.That's a retarded expression.
