Aleksey, I know it might seem as if we are all against you here... It is not that we're against you learning slang, it is that not everyone on this forum will be able to help you with that. As you can tell from this thread so far, none of us are big users of UK slang and as Hanna has explained it can be very local specific.
On this forum we try to correct one another's mistakes in both English and Russian (and German and Spanish...) as I have done above with two of your postings and we won't be able to help you as much if you are writing in UK slang. Additionally, as you are still having troubles with May vs. Would and writing sentences in English without slang... maybe you should focus on learning "proper" English first and wait just a little bit longer before you dive into the world of slang???![]()
