German for "NO". Usually used when one is frustrated to such a great extent that a normal english cuss word won't do. To be used sparingly and with vigor and strength.
NEIN is a word that acts as every known cuss. (Also translates to "NO" or "NEVER" in German)
Usually said whilst yelling or with vigour. Not to be confused with "Nine" or "Nien" (Nien is for dumbasses)
Me: Uhh boss... the Jews are here...
Hitler: NEIN NEIN NEIN NEIN NEIN!
