Firstly, slang is inevitable and crucial part of any language. Or you can claim that you have never ever used slang in your speech?

Secondly, what questions do you expect to come up here? There is no suprise that there are a lot of questions about slang being asked here. Think about it, if a word is used in its literal or usual and normal figurative sense, you can easily understand the word or effortlessly look it up in a dictionary. But this is the whole new story if you ran across a slang word or a slang expression. You can't understand it, even though you might be already familiar with the word or words. You probably can't look them up in a dictionary because they usually don't contain slang words or slang meanings of usual words. So what are you going to do? Of course, you're going to check up with native speakers on these matters.

Third of all, how is a non-native Russian speaker supposed to know whether they came across a slang word or expression? Of course, there might be some clues to determine a word or expression to be slang, but there mightn't be. That leads us to the fourth statement.

Fourth of all, this has to be a moderator who organizes all slang related questions into a slang section of the forum. But would our moderator not mind this extra (and maybe absolutely inapt) work?
