Morphology

knuckle + sandwich

The phrase uses a humorous metaphor (a 'sandwich' made of 'knuckles') to mean a punch, which has no literal or compositional link to the constituent meanings 'knuckle' (finger joint) and 'sandwich' (food). An average B1 learner who knows the words would be unlikely to infer the idiomatic threat/punch sense without prior exposure, so the expression is unpredictable and language-specific.

Etymology

The saying knuckle sandwich creates a strong image: imagine someone's knuckle as the filling of a sandwich pushed into another person's mouth. That's why people use it as a joking or threatening way to mean 'a punch' or 'I'll punch you'.
