Ballyhoo is all about being loud and flashy, creating an attention-grabbing spectacle. The term originated in early 20th-century slang to describe the loud carnival barkers yelling out exaggerated pronouncements when trying to drum up a crowd for a sideshow or attraction. Over time, it came to mean any hype or commotion to promote something. Using the word as a noun, you could say, "Despite all the ballyhoo, the movie was a box office flop." As a verb, you might say, "The bookstore ballyhooed the arrival of the last book in the popular series."
