The word badass has both negative and positive connotations, unlike the separate words bad and ass suggest. The positive meaning describes something impressive, admirable, and cool. The negative meaning refers to something frightening and tough.
The tail fins on the 1959 Chevrolet Impala (here in La Habana Centro) are badass. Fins started to appear on American cars in the early 1950s and peaked at the end of that decade. The pinnacle is the 1959 Cadillac Eldorado Seville. The fins supported the concept of design obsolescence; although quite technically similar, the cars and their fins grew bigger every year, so that customers could clearly see the difference between the models.
The geometric-distortion aberrations* of the Nikon 24-70 f/4 S for the Z6 and Z7 mirrorless cameras are definitely badass, whether or not they are a matter of concern will be the subject of this post.
