an antisocial misdeed in violation of the law by a minor
a tendency to be negligent and uncaring; "he inherited his delinquency from his father"; "his derelictions were not really intended as crimes"; "his adolescent protest consisted of willful neglect of all his responsibilities"
a pernicious and malign influence that is hard to get rid of; "racism is a pestilence at the heart of the nation"; "according to him, I was the canker in their midst"
