I'm sorry if there should be some profanity in this thread, but that is the matter of interest. I'm curious to find out, if there excists other examples like those I am about to write. There is a normal tendency in all languages to "disguise" bad words, with a similar, so called, noa word. These can be constucted in many ways. One common way is through alliteration. Хуй -> хрен Бляд -> блин Do you know any other example in Russian where this is the case?
