Seeming indifferent or uninterested, often associated with an unnatural calm and relaxed nature in an otherwise tense situation.
If you watch anime, Saitama from ONE PUNCH MAN is the epitome of a nonchalant personality when he's shown with his animated face.

He just ended his relationship of 3 years, yet he's so nonchalant about it.
