The term sammich describes any sandwich that is out of the ordinary. A sammich can be an exceptionally delicious sandwich, made with great care and planning. On the other hand, a sammich can also be an extremely ghetto sandwich, made by a desperate, hungry soul.
A sandwich that takes 10 minutes to prepare or contains three or more layers is usually considered a sammich. The microwaved butter sandwich, lettuce sandwich, or grilled cheese sandwich made with an iron are all considered sammiches.
