The mini bottle (50 ml) of Jagermeister, stored inside one's pillowcase for when you wake up in the middle of the night and need an extra drink to get back to sleep.
I woke up for a midnight shit and couldn't fall back asleep, so I fished in my pillowcase until I found the Jager, downing the tiny bottle for a little Hawaiian Nightcap.
