«زَيِّ كْلَابِ السِّكَّهْ يُعُضُّوا عَ الْمَاشِي»

The saying portrays a person for whom causing harm is second nature. Like stray dogs that snap at whatever crosses their path, such a person wounds others almost automatically, without planning it or needing any special reason to do so.

The emphasis falls on effortlessness and habit. The harm comes casually in passing, as part of ordinary movement, not as a deliberate attack on a particular passerby; it is a by-product of temperament, surfacing wherever the person goes.

Used to criticize someone whose spite has become habitual, hurting others offhandedly as they go about their day. Comparing a person to street dogs is insulting, so aimed at a specific person it is a sharp rebuke suited to complaint or gossip, not polite conversation.
