Morphology
eat + one + hat
The intended meaning (expressing extreme improbability or a vow to do something absurd if an unlikely event occurs) cannot be derived from the literal meanings of 'eat', 'one's', and 'hat'—the image is an absurd hyperbole whose conventional meaning is idiomatic. This is a fixed, conventionalized English idiom whose metaphorical sense is unpredictable and unlikely to be guessed by a B1 learner who knows the parts but has not encountered the expression.
Etymology
The idiom eat one's hat comes from a funny, literal picture: someone saying they will eat their hat if something happens. So it is a joking way to say you think that thing is 'very unlikely'.
