عامل لمونه فى بلد قرفان

Amel lamouna fi balad arfan

Translation: He thinks he is like a lemon in a town that is nauseated.

Meaning: Lemon was believed to be a cure for nausea, and therefore a town suffering from nausea would be desperate for a supply of lemon. So if you happen to have a particular skill that is in short supply, everyone will welcome you – with the same desperation a nauseated town would welcome a batch of lemon.
