Each of these words has its own nuances and connotations, but they all essentially mean the same thing: expelling the contents of one's stomach forcefully and involuntarily. Whether you need to describe a queasy feeling or an actual bout of vomiting, these synonyms offer a range of ways to express this unpleasant experience.
