All these questions to russians you wanted to ask!
So, "vranyo" essentially refers to dishonesty, and is often used in a casual or informal context.
"Ochkovtiratelstvo", directly translated as "Rubbing in someone else's glasses", is akin to terms like "eyewash", "window dressing", or "hot air". This phrase is used when you're trying to convince someone that something is incredibly luxurious, excellent, or high-quality, even though you're fully aware that it's actually of poor quality.
I remember it was a good video , but his definition of "vran'yo" was unnecessarily narrow. "Vran'yo" is pretty much as wide as "lies" in English, not specifically bullshitting, no straight face required, no requirement of doing it systematically, no nothing. So this specific part left me fairly disappointed.
His definition of "Ochkovtiratelstvo" is solid.
Vranyo (Russian: враньё) is a regular informal word for lying - the more formal is lozh (ложь)
Ochkovtiratel'stvo (Russian: очковтирательство) is one of the swear words on the lighter end, and quite uncommon at that, mostly applied to when a person is blatantly and stubbornly lying in an argument. Probably the most common swear word for lying is pizdyozh (пиздёж).
