Depending on the force of the return, this occurrence could be considered regurgitation or vomiting. If the food in the mouth is not forced out of the mouth, perhaps leaves a bitter taste in the back of the throat or heartburn, the occurrence would be considered regurgitation. If the food is violently forced out of the mouth, perhaps with nausea beforehand or dry heaves afterwards, the occurrence is considered vomiting.
