I've never heard the term "tuck it in" with respect to food, but it's definitely explains the process that occurs with a Big Mac.

Personally, what causes me to not be so pleased with a Big Mac was a story on television not too long ago about fat farms here in the US. Almost everyone they talked to was over 400 pounds, and had some story about their relationship with Big Macs.

>Eg: The light goes on when I flick the switch. That is the conclusion that concerns me. How and why "the journey" happened to cause photons to illuminate my dark office does not matter a jot. Same with a Big Mac- actually if you actually checked how that thing came to be, you might not be so pleased to tuck in.
