«عَنْدُه بضَاعَهْ وِالنَّاسْ جَوَّاعَهْ»

The saying pokes fun at a person who is puffed up about his own possessions. He acts as if he alone holds the goods everyone needs, and as if the people around him were starving and had to come to him for their daily bread. That hunger exists only in his own imagination.

Its point is inflated self-regard and condescension toward others. It is not a neutral remark about trade or a real food shortage. The imagined merchant does not simply have something to offer. He lords it over others, treating their supposed need as proof of his importance. The speaker exposes that attitude as vain and overbearing.

Use it to deflate someone who acts self-important because of what they own or control, as if everyone else depended on them. It suits teasing or criticism among people who know each other. Avoid it where a neutral description of a seller is wanted.
