To talk like a russian

To tell lies, especially when others know the truth.

Originates from the way how russian propaganda lies to everyone about their actions by twisting the truth. Like when they shelled Ukrainian cities and blamed Ukrainians for that. In other words, if russians are talking about it, they are most certainly lying.

Have you heard about James?
YES! I can't believe he decided to talk like a russian about what happened to him in Vegas!
I know, what a liar.
