Sprezzatura

Juno MacGuff: I think I’m, like, in love with you.
Paulie Bleeker: You mean as friends?
Juno MacGuff: No, I mean, like, for real. ‘Cause you’re, like, the coolest person I’ve ever met, and you don’t even have to try, you know…
Paulie Bleeker: I try really hard, actually.

confirms the sprezzatura idea of trying really hard not to look like you're trying really hard - see http://en.wikipedia.org/wiki/Sprezzatura


INFORMATION FROM ABOUT.COM

Definition:

The rehearsed spontaneity, studied carelessness, and well-practiced naturalness that underlies convincing discourse. (The opposite of sprezzatura is affectazione--affectation.)

Etymology:

Coined by Baldassare Castiglione in The Book of the Courtier (1528): "[T]o avoid affectation in every way possible . . . and (to pronounce a new word perhaps) to practice in all things a certain Sprezzatura [nonchalance], so as to conceal all art and make whatever is done or said appear to be without effort and almost without any thought about it."
