Eating any delicacy over and over for several days will surely become nauseating, to continue further would be sickening.
Luncheon meat isn't even a delicacy, it's just a bomb in the form of meat.
Since ten years ago, when some warped foster-father handed him loads of packages of luncheon meat, burritos filled with black beans and rice, artificial butter and started the wilderness survival journey, the boy had remembered the taste. Later when he went to school, the school, in order to make the students' life as close to camps and battlefields as possible, sometimes would feed them just battle rations for a few days. Even in daily life, the chefs would serve various dishes featuring luncheon meat with a sinister grin on their faces.
In the battlefield, soldiers can only eat this!
No local food is allowed deep in enemy-occupied areas!
Luncheon meat is a soldier's soul!
