A term used in the US Army to denote extreme uselessness. It is directed toward something or someone that is the figurative equivalent of the literal
hot sloppy pile of shit that a gob of soup between two pieces of sandwich bread would be.
So the implication here is that the object of discussion is 'Fucked up like a soup sandwich.'
Equivalent expressions in the civilian world are:
Tore up from the floor up.
Useless as tits on a boar..
and so forth.
Drill Sergeant: "Private you can't do anything right, you could break a goddamn crow-bar. Why I couldn't trust you to remove the lint from the back side of my ball sack with a piece of goddamn hundred MPH tape. You're about as worthless as a soup sandwich."
Drill Sergeant: "You are the lowliest goddamn example of hot garbage I have EVER seen. You look like a goddamn soup sandwich, that uniform looks like you
pressed it under your mattress springs, and those dusty ass boots look like you shined them with a
snicker bar and a goddamn green pad. That is goddamn un-sat, Private. Report to my office immediately following this formation to be
skullfucked appropriately."
