Antisocial behavior is behavior that violates social norms at some level. This may be as minor as picking one's nose or as serious as serial murder. However, in casual use, the term typically refers to relatively minor degeneracy that disturbs the peace or otherwise noticeably disrupts the social order: including being a loner, lacked of respect, vandalism, littering, cheating, stealing, complaining, lacked of sense of humour and grumpy.
