1.
A pun on 'nap time', except with one person catching Z's with their head in another person's lap.

Usually happens when watching a movie or somesuch and the relationship is comfortable/intimate enough to allow for the tired one to fall asleep in the other person's lap.
"I can barely concentrate on this flick anymore and I'm dead tired to boot. It's lap time."
