Morphology

fat + chance

Although the constituents 'fat' and 'chance' literally suggest a large likelihood, the phrase is used sarcastically to mean the opposite—that something is very unlikely. This ironic inversion is idiomatic and not predictably derivable from the parts, so a B1 learner who only knows the words would likely misunderstand it.

Etymology

Fat chance probably started as a joke on the older phrase 'slim chance'. By saying the opposite in a mocking, joking way, people made a strong, funny image, so fat chance means 'very unlikely to happen'.
