01

"louse / lowlife / snitch"

A nit — a louse egg. Calling someone this means they're small, parasitic, disgusting, and beneath contempt. In Russian prison slang, it specifically means an informant, similar to 'козёл' but with added disgust. The smallness of a nit is part of the insult: you're not even a full parasite, you're the egg of one.

About a traitor or snitch: 'Он гнида, сдал всех' (He's a louse, he ratted everyone out).
