When one spends a night or a few nights, staying up late/ not sleeping at all, with someone called Dan.

The result is feeling tired and lethargic for several days after.
Friend: What’s got you looking so tired? I didn’t think you went out this weekend?

Me: I didn’t, Dan came over and we stayed up all night. I’ve got a Dangover.
