Bodacious

Bodacious is commonly defined as meaning variously blatant, audacious, impressive, remarkable or attractive. As you can tell from its wide-spectrum definition, this American word is one of those wide-ranging superlatives to which speakers turn when they want to say that some quality is present in large degree; that quality might be unreasonableness, impressiveness, insolence, or (most recently) female attraction, specifically big breasts. This last meaning seems to have become widely known in the middle 1980s after it was employed in the film An Officer and a Gentleman in 1982. Another film, Bill and Ted’s Excellent Adventure of 1989, contributed to its growing nationwide popularity.
