Did you know?
Boffo made its print debut as a noun referring to something great: a solid joke or a good punch line. It did so right around the same time—the 1930s, at the dawn of Hollywood’s golden age—as boff, a noun with an identical meaning thought to perhaps come from “box office.” Within a few years, boffo began to be applied adjectivally to things that, like a good joke, were a big hit: performances, all-star casts, movies. To this day it is used mostly in the context of performing arts, spectator sports, and other entertainments.
