How to say "sickening" in Japanese

• きしょい
  i-adjectiveA slangy shortened form of 気色悪い, covering the 'gross' sense of sickening: a blunt, casual reaction to something disgusting, at home in everyday conversation.
• 胸糞が悪いむなくそがわるい
  expression, i-adjectiveSickening in the physical, nauseating sense: it presents disgust as a visceral reaction, the sick feeling in the chest that something revolting produces.
• 気色悪いきしょくわるい
  i-adjectiveSickening with a weird streak: disgust mixed with unease at something strange or off-putting. Choose it when plain 'disgusting' misses the odd, unsettling quality of the thing.

  He gives me the creeps.
• 気色の悪いきしょくのわるい
  expression, i-adjectiveThe attributive form of 気色悪い, with の: the same weird, disgusting, sickening sense, used when the expression sits before the noun it describes.
• 胸糞悪いむなくそわるい
  expression, i-adjectiveThe same expression as 胸糞が悪い, written compactly without が: revolting, nauseating disgust felt viscerally. Either form works when something makes you feel sick to your stomach.

For 'sickening', 「きしょい」 is the slangy 'gross' choice, the two 胸糞 expressions convey nausea-tinged disgust, and the two 気色 expressions add a weird, off-putting nuance, 「気色の悪い」 being the noun-modifying variant; all are less common.
