A strong feeling of dislike for somebody/something that you feel is unacceptable, or for something that looks, smells, etc. unpleasant.
Disgust is a very interesting emotion. I don’t know if it is learned or not. We can see babies making disgusted faces when they eat something so it would put it in the "natural feeling". But at the same time, we see young kids doing really disgusting things for adults like playing with their own poo. Some scientist even say it is learned. Or maybe it is just a problem of definition. The Oxford’s dictionary defines it as "a strong feeling of dislike for somebody/something that you feel is unacceptable, or for something that looks, smells, etc. unpleasant. So if an infant really dislikes something, he is disgusted, he is just not disgusted by the same things as adults. Note that we can also be disgusted by something moral like in the example below.
Example: Your vulgar remarks disgust me.
