Making someone hostile; actively provoking opposition or hostility in someone.
Present participle of antagonize, formed with -ing suffix from Greek anti- + agonizesthai. The -ing form can function as a noun (gerund), adjective, or part of continuous verbs.
The -ing form of verbs often carries a sense of ongoing action, so 'antagonizing' implies a continuous process rather than a single act—which makes it descriptive of personality types (he has an antagonizing manner) as well as actions.
