- adjective fashionable. A vogue term of the early to mid-1960s which, in its sense of stylish or up-to-date, is still used by the middle-aged in particular, but now sounds dated. It derived from the phrase ‘get with it’, an essential item of pre-World War II jive talk and post-war beatnik parlance. In its sub-sense of ‘on the ball’ or in touch with events, the phrase may be used by speakers of all ages.
