What is Post-drunk?
1.
The kind of drunk where you feel really slow & unmotivated, but eventually you work yourself up into a frenzy, only to fall back off again; this cycle usually repeats itself. You tend not to talk much, if at all. This kind of drunken experience usually lasts longer than most other types, and people who don't get drunk that often have no idea this kind of drunk exists.
"I'm post-drunk, but last night I was prog drunk. I'd explain, but it's a bit complicated."
