Here is a short one from Judge Posner: “The parties, illustrating lawyers’ typical insouciance about quantification, have not told us what the retired pilots’ unsecured claims are likely to be worth.” In re UAL Corp., 468 F.3d 456 (7th Cir. 2006).  Insouciance means characterized by a nonchalant or cheerful lack of concern.

As an aside, I challenge our readers to begin using “chalant” as a word; if one can be nonchalant, one should certainly be able to be chalant.
