look up any word, like darude - sandstorm:
A pejorative acronym, usually ageist, referring to those who are 'not sound'.

If the term is used in an ageist manner, any inquisitive NS can be told that this acronym refers to 'new season'. This allows for flagrant usage of the term among 'OS' (which designates the opposite. This acronym can refer to 'Old Season', 'Old School' or 'Only Sound').
