The discrete location (usually somewhere "outback") where you or someone you know always pours out all the old coffee. Other things can be included such as, old mop water, hot dog water, but for the most part it is just old coffee. If you ever go try and dig up a coffee graveyard site, you will find that you have to dig about 3 feet deep before you are past the coffee oil.
Is this a fresh pot?
No, just make another.
Where can I pour this out at?
Out back, you'll see the coffee graveyard.
