slungover

Feeling like you're hungover but annoyingly due to a lack of sleep rather than drink.

I literally have no idea what is going on today, I'm so slungover

slungover

when you nap too hard and wake up feeling hungover, but you didn't drink at all.

Person 1: Where's Bob? He was supposed to be here five minutes ago.
Person 2: He just texted me. Says he just woke up from a really good nap, but he's really slungover.
