«اِلْعِيبْ مِنْ أَهْلِ الْعِيبْ مَا هُوشْ عِيبْ»

Faults or disgraceful conduct from people known for them surprise no one. The saying does not excuse the wrongdoing; it denies that the act is shocking, because the offenders' reputation already predicts it. Nobody treats it as a fresh scandal.

In a narrower sense, the saying applies to insults and slander. Abuse from a habitual mudslinger carries no weight and should not hurt its target, because the habit itself reveals the speaker's baseness. The stain lands on the speaker, not on the person being attacked.

Use it to brush off a rude act or insult from someone already known for that behavior. It reassures the target or explains why no one reacts. Because it brands the offender as habitually disreputable, it is itself insulting and pointed if said within their hearing.
