look up any word, like timebomb:
 
8.
The act of eating so much delicious food that you want to sleep for a long time.

9.
An excuse to blow off work after eating too much at lunch.
I think I'm gonna crawl under my desk after that heaping helping of mashed potatoes, because I can already feel the food coma creeping up on me...
