“Dishin’ the dirt” basically means sharing the “juicy info” you learned about someone. Maybe the intent isn’t to directly cause damage, but by keeping the gossip alive, it continues to spread and taint the image of the person it’s about.
Proverbs 20:19 tells us that a gossip betrays a confidence; so avoid a man who talks too much.
James 5:9 says, “Don’t grumble against each other, brothers, or you will be judged. The Judge is standing at the door!”
