The point at which tomorrow will officially suck if you have to be conscious before 2pm for any reason. Which, sadly, most do.

Let me die.

The time people normally notice after spending an entire night playing video games.

the time right now

When the clock strikes 4 it’s a sign that you need to get yourself to sleep

When you have to poop, but do it exactly at 4 in the morning. Usually when someone outside of your family or someone you are not used to, stays at your house/vice versa and you don't want to drop a deuce while they are awake

( n. ) a time when people who are actually up this late are either heartbroken or in love
