How to say "hysteria" in Japanese

• ヒステリーCommon
  nounCovers hysteria in the sense of a fit of uncontrolled emotion, with someone shouting, crying or losing self-control. As the common word, it is the safe default choice in your own speech and writing.
  トムはすぐにヒステリーを起おこすので、みんなが敬遠けいえんする。↗

  Tom loses his temper so easily that everybody avoids him.
• ヒス
  nounA shortened form of ヒステリー with the same meaning. It is less common, so recognize it when you hear or read it, but prefer the full word in your own Japanese.
  お願ねがいですからヒスを起おこす前まえに話はなしは最後さいごまで聞きいてください。↗

  I'm begging you, before freaking out on me listen to the end of what I have to say.

Both words mean hysteria as an uncontrolled emotional outburst; use the common full form 「ヒステリー」 in most contexts, and treat 「ヒス」 as its less common shortened form, one you mostly need to recognize rather than produce.
