«زَيِّ الْبَرَاغِيتْ يِتْلَمُّوا عَ الضِّيفْ»

The saying compares people to fleas that settle on a visitor, describing a group that converges on someone newly arrived. The fixed point is the swarming itself: many people drawn at once to a single newcomer, pressing close around them.

Two readings remain open. The crowd may be people latching onto a stranger to get something from them, or people who descend on a household whenever a guest comes, hoping to share in what is served. Either way the flea comparison disparages the crowd, while the guest's own standing is left open.

Fits informal comment on people who swarm around a visitor or newcomer the moment they appear. Since it likens them to fleas, it is mocking; use it about such a crowd rather than to their faces, and keep to situations where the swarming itself is the point.
