«كُل وَاحِدْ لُهْ بِدِنْجَانْ شِكْلْ»

The saying points out, with playful exaggeration, that no two people think or choose alike. Its eggplant is an everyday image, and its "shape" means a contrasting kind rather than mere physical form: each person holds an idea or preference unlike everyone else's, so expecting uniform opinions is unrealistic.

In practice it works as a shrug at human variety. A speaker may offer it to explain why a group cannot agree, to excuse someone's unusual taste, or to suggest that differing opinions are normal and need not be forced into a single view.

Use when people's views, habits, or preferences diverge and you want to accept that divergence lightly rather than argue it. It suits remarks about relatives, friends, or colleagues who each insist on their own approach, and it can soften a disagreement without declaring anyone wrong.
