revolted at (someone or something)
Feeling intense and shocked disgust, repugnance, or offense because of someone or something. We were revolted at the squalor within the refugee camps. I always remember being revolted at my great-grandmother at the time because of her sickly, aged body and smelly, scary room. I was revolted at the thought of having to spend my weekend working.
revolted at someone or something
sickened by someone or something. I was revolted at Frank and his behavior. We were all revolted at the scene of the bloody highway accident.
