Emetophobia is an excessive fear of vomiting. Emetophobia is often classified as a Specific Phobia, however, there is also thought that it could be considered under the umbrella of Obsessive Compulsive Disorder.

We can probably say with quite a bit of confidence that none of us really like vomit. The difference between individuals with and without emetophobia is that those with emetophobia truly fear vomit and the act of vomiting.
