«قَالُوا: يَا جُحَا، مِرَاةَ ابُوكْ تِحِبَّكْ؟ قَالْ: هِيَّ اجَّنِّنِتْ؟!»

The joke turns on the reply of Juha, a stock comic figure of folk anecdotes: asked whether his father's wife, his stepmother, loves him, he treats the idea as proof she must have gone mad. It is a punchline, not a personal statement.

By extension, the saying voices a traditional folk stereotype that a woman resents her husband's children from an earlier marriage. It mocks rosy claims of warmth in such relationships, but it reflects that inherited view rather than any factual truth about stepfamilies.

Said with wry humor about stepmother–stepchild relations, or to dismiss as absurd the idea that someone with a built-in reason for resentment feels real affection. Suited to informal joking; it reflects a stereotype, not a fact about families.
