What is a word for someone who hates or intensely dislikes one person? Misanthrope (hatred of humankind) is exactly what I'm looking for except it is too broad. This is a word I intend to use humorously, if it helps.
Example sentences:
- Sarah is a ________ because she doesn't hate anybody but Donald Trump.
- Ben is a poly-_________ because he hates everyone on his swim team.
