A timestamp that people randomly put on porn or otherwise sexual videos. Usually, these timestamps can be found on tons of feet and shoe-play videos, but most notably, school shoe-play videos, because for whatever reason someone thought it would be a good idea to put a camera in the back of a classroom and then upload it to YouTube for creepy and wrinkly old folk to jack off to.
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.
