The groggy, tired, unable-to-open-one's-eyes feeling that one can experience after a midday nap.
I fell asleep on accident, and not only did I lose the hour I slept for, but I lost another hour or two to the nap hangover.

The headache, numbness, and discomfort that is experienced by a person when a power nap turned into a 4-hour nap marathon. It's when a 30-minute nap turns into a 4-hour nap that is not quite long enough to qualify for a true sleeping session.
It's 7PM on a Friday night. You decide to take a 30 minute nap, so that you'll have more energy for the weekend's events. 4 hours later, the intended 30 minute power nap turned into a 4-hour nap marathon.

Eddie: What time is?

Jane: It's 11PM

Eddie: Oh man! I was supposed to wake up before 8PM to meet up with the guys, but now I have this crazy headache.

Jane: You are experiencing a naphangover.
