John Derbyshire:

Neologism
I have just invented a word.

A reader wrote in with a cute story, then signed off with: "I don't have a pithy closing remark..."

I replied that those pithy closing remarks don't always come when they're needed. In my case, in fact, they generally come a fraction of a second after I've hit the "send" button.

And this fraction is called (drum roll): a PITHISECOND.

Need more coffee.

I think the pithy closing remark about the coffee is the real selling point to that post :)
