How to say "outrageous" in Japanese

• 大それただいそれたCommon
  pre-noun adjectivalCovers outrageous plans, ambitions, or ideas — something wild and wildly overreaching. Think of a scheme so bold it borders on crazy rather than an act that offends others.
• 言語道断ごんごどうだんCommon
  na-adjective, no-adjectiveFor conduct that is morally outrageous and beyond excuse: scandalous, preposterous behavior that invites condemnation. It is a four-character idiom expressing strong outrage at someone's actions.
  きみの言語げんご道断どうだんな行おこないを恥はずかしいと思おもう。↗

  I am ashamed of your despicable deed.
• 論外ろんがいCommon
  na-adjective, no-adjectiveSays a proposal or idea is out of the question — not even worth discussing. The 'outrageous' sense is secondary; use it when rejecting something as beyond consideration, not to describe shocking conduct.
  この前まえの娘むすめは口述こうじゅつ内容ないようを筆記ひっきするのも無理むりだった。速記そっきなんて論外ろんがいさ。↗

  That girl couldn't take things down in longhand, let alone shorthand.
• 法外ほうがいCommon
  na-adjective, nounOutrageous in the sense of exorbitant — a price, fee, or amount so far beyond reasonable that it seems ridiculous or absurd. This is the word for outrageous costs, not behavior.
  私はこの自転車じてんしゃを法外ほうがいに安やすく買かった。↗

  I bought this bicycle dirt-cheap.
• 理不尽りふじんCommon
  na-adjective, nounFor treatment or demands that are unreasonable and irrational — outrageous because they defy fairness or logic. A boss's absurd, unjustified reprimand is a typical target of this word.

Use 「大それた」 for wild ambitions or ideas, 言語道断 for morally inexcusable conduct, 論外 for proposals beyond discussion, 法外 for exorbitant prices, and 理不尽 for unreasonable, unfair treatment.
