The dictionary link I gave is no longer an active website. For the time being it lives only in the Google cache. This dictionary appears to contain miscellaneous words, phrases and symbols that are not found in a normal dictionary. Users of the site were invited to contribute to the dictionary. The site also had a section for jokes, comics, games, downloads, a forum, chat and a kitchen. It looks like it was a friendly place for Russian users. There are many definitions that do not appear to be insulting. For example near the end of the list the symbol is defined as what I type to show that I smile.

I think MikeM and gRomoZeka are right. Maybe there was a person named Chubrik who was considered to be ridiculous by some, and so that is why that dictionary contains that definition. That is just my guess, I do not know.
