Something hicks from illinois say when they're referring to the time right after the sun sets.

Be home before darkthirty ya'll.

Darker than 0'darkthirty

Blacker than Pitch. The darkest morning you've ever driven on a very dark road, with no one, not even the moon to light your way.

"It is Darker than 0'darkthirty. That is darker than dark!"
