What is a word that rhymes with like but means the total opposite?

There's no single word that rhymes perfectly with "like" and means the complete opposite. However, you can get close with some options:

* "Unlike" is the most direct opposite, but it doesn't rhyme exactly. It rhymes with "strike," "bike," etc.

* "Dislike" is another option, but it doesn't rhyme perfectly either. It rhymes with "spike," "bike," etc.

* "Hate" is a stronger opposite and rhymes with "fate," "wait," etc.

Depending on the context, you could also use words like "loathe," "despise," or "abhor."

Ultimately, the best choice will depend on the specific situation and the intended meaning.
