Sea hog is a colloquial term for a large, aggressive person who dominates others in a group or conversation. Some synonyms for this term include blowhard, braggart, bully, loudmouth, and egotist. These individuals often exhibit a sense of entitlement and lack of respect for others, particularly those who are not as assertive. Sea hogs can create a toxic environment and make it difficult for others to communicate effectively. It is important to identify and address this behavior in order to improve group dynamics. Alternative terms such as "dominator" or "attention-seeker" may also be used to describe this type of person.
