Hey, a bit of off-topic, but I just love the way it's explained about Russian profainty language (not mine, found it on quora), but it's 250% true ))
While Russian profanity (mat, мат — originally матерная брань, máternaya brañ, meaning curses related to мать — mother [of a person or entity that is being cursed] — and genitalia) has only four major and three minor “strong roots”, it is unbelievably florid, ubiquitous and universal, thanks to almost infinite variety achievable with prefixes, suffixes, conjugations, declensions, and other intricacies of Russian language, together with milder profanity, semantic and phonetic substitutions, intonations and regular vocabulary. You can express literally any thought, term, condition or even complex philosophy using Russian profanity, and in stressful or dire situations that imply quick action, profanity dramatically shortens the length of what's needed to be said. There is a half-joking opinion that any success Russian speakers achieve on a battlefield or in emergency happens thanks to use of profanity instead of more socially acceptable ways of oral (or even written) expression. The aforementioned poem alone demonstrates about 4–5% of possible uses of Russian profanity, maybe even less, even though it consists largely of profanity and description of a violent intercourse with dreadful consequences.
Profanity is something you should know but abstain from using, especially if you are not quite proficient in Russian. While obscenities are an inseparable part of the language, under certain circumstances their use may cost you anything between social standing, official fine, heavy injury, and sometimes even life. That doesn't mean that everybody behave: profanity is an absolutely essential part of Russian lexicon for about 90% of population who can speak at all. I have decently trustworthy sources confirming that current supreme officials do not restrain themselves while off the record.
