In slang, old school can refer to anything that is from an earlier era. Old school refers to something that is fairly old and not very recent. Depending on the context and intent, the term can imply a high regard or respect, or be a pejorative. The term often describes music, clothing, games, language, or perceived norms of behavior and generally implies a vintage of at least 15–20 years, but could be considerably older. When used to imply a high regard for something, "old school" is applied to things perceived to be of timeless style, wisdom, or quality, or with wide acceptance in earlier times and continued value in the present.
