The specifics of Russian language is a plenty of suffixes and prefixes which can be combined together to get something more or less meaningfull. Such combinations mostly are not in vocabularies and are colloquial in some uncertain degree. So it is often difficult to say what is valid Russian word and what is not and what does a word mean exactly without context.

Anyway such long words are not common way of expressing ideas in Russian.
