Welcome, my dear friends of Russian abuse language. If you want to express your emotions without looking too rude or insulting others here are some tipps for you. They also will be useful if you visit Russia to communicate with some categories.
1. First of all you have to learn to say blya or Blyat` It is often used in the contracted form at the end of any phraze to make it empathetic. I.e Ty cho blya ( What the hell are you doing). Also Russians use it when the stub a toe or feel any kind of pain. Some people are realy blyat` addicted and they use this word for the most banal things. Ia blyat poshel blyat v mazazin bliat i kupil blyat ogurtsov. I went to the shop and bought cucumberries. This word is meat in dumpling of Russian mat
2. The second one might be the first foreigners learn in Russian. Khui means a cock or a pennis. Idi na khui may sound silly in English translation Go to pennis,. But Russian mat is interesting by a plenty of derrivatives. Okhuet means to be extremely surprised. For example if you fing a wallet with thousand dollars on the street or It may be said to someone with abnormal behaviour "Ty chto Okhuel" for example when you friend takes your thing without permission . I am feeling khuevo= I am not well. Khuinya = a bullshit
3. Pizda is a famale sexual organ. But it may enrich your vocabulary and help you swear more creatively. If you are tired of sending people to pennis just tell them Idi v Pizdu Go to cunt. It will be nearly the same
4. Finaly we will learn how Russians call someone very inpleasant. It is commonly used for males. Mudak is a synonim of dickhead or an asshole. It is vitaly important when you drive in Russia. If someone cuts you off just shout out mudak of your window. If you mudak is little you just call him mudachok. If he is fat mudak becomes mudilo.
So now you know how to swear like a Native Russian. Welcome to Russia !
