Etymology

The word "tubular" derives from the Latin "tubus" (tube) + the suffix "-ular," which forms adjectives meaning "resembling" or "pertaining to." Originally describing objects with a cylindrical shape, it was adopted into 1980s surf/skate slang to mean "awesome" or "radical," metaphorically evoking the smooth, flowing curves of a wave or pipe.
