Jason: Damn, you look dead. What happened?
Kelly: Ugh... I was sleepcrastinating hardcore last night. I got through the first two seasons of Popular Vampire Drama and read some books on faeries, but I don't remember any of it.
Jason: Your sleepcrastination has gotten outta hand, yo.

The act of putting off going to sleep for no good reason, even though you’re completely exhausted and have to wake up early the next day. Often includes mindless scrolling, binge-watching, or doing literally anything except sleeping.
I was dead tired at 10 p.m., but somehow ended up watching conspiracy theory videos until 3 a.m. Total sleepcrastination.
