Post-scran-scran

A meal eaten after the main meal.
It might be just a snack or another entire meal depending on your hunger, appetite and stamina.
Always savory and not sweet like duff, pre-scran-duff or post-duff-duff.

A couple of hours after a meal you might get the munchies and order in a kebab, or a curry.
After a meal out in a fancy restaurant you might still be hungry and go for some post-scran-scran at macdonalds.
