UK English has a phrase ‘cushy number’, referring to an easy, perhaps well-paid job, or any fortunate circumstance.
Chambers Dic 1977 gives cushy, adj, = easy and comfortable: not dangerous. [perh. Hind. khush = pleasant; khushi = happiness]
Right, but it’s not “cushy” we’re interested in, it’s “cush.” The abbreviated form has a life of its own, both as a noun and as an adjective, that does not seem to be accounted for in the dictionaries I checked.
