Crap-a-nap 

When one passes out while taking a shit.

Person 1 : Where's James, haven't seen him in a while.
Person 2 : I think he's taking a crap-a-nap.

Drop a crap and take a nap 

To use the restroom just for the sake of getting a break from work, especially if you stay there for an unusually long time.

Work's been so hectic today. I think I need to drop a crap and take a nap.
