While browsing the HTLAL forum, I came across a Russian podcast I was unfamiliar with. Called Очень по-русски, it focuses on “REAL Russian language: slang, common expressions, idioms and even swearwords.” Here’s a bit more from the About page:
This site aims to fill this gap at least a little and to overcome this unfortunate injustice. Russian slang, idioms, common expressions – I share with you the Russian language, which you will not find in standard textbooks. The language that I hear every day, that I and people around me speak every day. There are also expressions that I personally do not use and do not advise you to use – rudeness and swearing are not the best ways to communicate. But they are also a part of my native language and therefore they are here.
New podcast episodes are published every Monday and Thursday.
Most episodes are around two minutes long, and a full transcript is provided for each one. Certainly worth checking out, particularly for intermediate to advanced learners.
