Have been thinking: how many different terms are there to indicate an informant?

Rat
Stool pigeon
Snitch
Squealer
Turncoat
Grass or supergrass (British terms, as far as I know)

Any others? In Russian the term "stukach" literally translated would be "knocker".


Willie Marfeo to Henry Tameleo:

1) "You people want a loaf of bread and you throw the crumbs back. Well, fuck you. I ain't closing down."

2) "Get out of here, old man. Go tell Raymond to go shit in his hat. We're not giving you anything."
