Roughly translated as "The clique that loves the letter k, which is not caught easily." The name of an imaginary band that would be real if we all lived together.
Person A: Have you heard of that awesome band, the Coterie of the Elusive Letter, K?
Person B: No.
Person C: They don't really exist... but they would if the Coterie lived in the same country. BWAHAHAHAHAHA I AM PERSON C!!!!!
Either liquid niquil or any liquid drink with melatonin, Ashwaganda or other sleeping aids in a liquid form. If warm tea helps you get to sleep that could be sleepy juice too.
I could not sleep so I chugged some sleepy juice and now I'm so tired and sleepy.
