Insouciance

The cicada has represented insouciance since antiquity.

A shirt cropped above the waist is only for those with a chiseled midriff or an insouciance for the aesthetic opinion of others.

So Gelernter, with an insouciance he now regrets, also chose a Lovelace as a namesake—Linda, the lead actress in "Deep Throat."

She almost felt insulted by [the wild boar's] insouciance as it rooted in her grove.
