imperishable
Enduring or occuring forever
George Herbert emphasies the imperishable nature of virtue
imperishable night
When you have a day expected to be 24 hours in length or more without sleeping. Named after the Touhou game where you freeze the night just to find that one person who put up a fake moon.
My day began at 7AM, with me flying out of Toronto for Dublin at 5PM. It was 6AM the next day when I arrived, and I didn't fly to Glasgow until 1PM. I didn't get to the hotel until 7PM. That was one heck of an Imperishable Night.
