«زَيِّ بِرْكِةِ الْفِسِيخْ كُتْرَه وْنَتَانَهْ»

The saying pictures the pit where fesikh, a pungent Egyptian salted fermented fish, is buried to cure: the more fish piled in, the worse the stench rising from it. Sheer quantity brings no benefit, only a heavier reek, so crowding and foulness grow together.

Applied to people, it scorns a group gathered in one spot whose numbers seem to multiply their filth or bad conduct. The speaker implies that such a crowd is worthless and repellent, and that adding more members only makes it worse.

Use it as a sharp, mocking remark about a crowded place or group seen as dirty or unpleasant, where numbers only add to the mess. Aimed at real people, it is a serious insult likening them to rotting fish; it suits informal, critical speech, not polite company.
