When you find yourself in a date with someone who bores you to the point that you find yourself asleep with your eyes open.
Paige: Dang, the guy last night who took me to dinner was such a bore. He caught me datenapping right during the entree.

Jill: Ya, I always used to suggest movies instead of dinner, in the event the guy was a loser, so I could catch up on my datenaps, especially if I did not get my meetnapping that day at work.

Get the datenapping mug.
When you are on the worst and longest date ever with a person that you didnt want to go out with anyway but did out of obligation, and they picked you up, so you cant leave and you feel too bad to tell them to take you home, so you are forced to endure the entirety of the date.
Girl 1:"How was your night last night?"
Girl 2:"Oh my god! That guy who had been asking me out everyday for three months totally datenapped me! He took me mini-golfing, then to a 12 course meal. He dragged me to a movie, ice-cream and then drinks after. It was the worst night ever!"
Girl 1:"Wait! Datenapped?! is that like date-ra..."
Girl2:"Oh god no! Not at all!"
Girl 1:"Oh thank jesus"
