The Empty Feeling Edit Meaning

1.

There's an actual word for this, but here's the slang. It's that feeling you get after you've completed a great video game and have nothing to do, or finish watching a series you loved, either TV series or on DVD. It's a feeling that makes you compile its ending, linger for more, but in all of it, you're still happy you've completed it.

I CAN'T BELIEVE IT ENDED LIKE THAT!! Oh amn, I'm gonna have TEF for days!
