How to say "slang" in Japanese

• 俗語ぞくごCommon
  nounCovers slang as part of colloquial language: informal words and expressions used in casual everyday speech. This is the straightforward choice when you mean 'slang' generally, rather than secret in-group vocabulary.
  できることなら俗語ぞくごは使つかわないようにしなさい。↗

  Don't use slang if you can help it.
• 隠語いんごCommon
  nounCovers slang only in the argot or cant sense: a group's secret language, used so outsiders cannot understand. For ordinary informal slang, this is seldom the word you want; it means 'secret language' or 'jargon'.

Use 俗語 for slang in its ordinary sense, informal colloquial language; choose 隠語 only for the secret-language sense — argot or cant, the vocabulary of an in-group meant to keep outsiders from understanding.
