I wouldn't call myself polyglot, I would be a stereoglot, or even monoglot, but I am sure most of the people here are closer to be called Dolby Surround glot (5.1).
The reason why I am a stereoglot is because I know basically two sides - my own language fully and completely and all the rest languages but in very small parts.
A polyglot is someone with a high degree of proficiency in several languages. definition by Wikipedia
Another option for Dolby Surround glot is:
Hyperpolyglot.
A hyperpolyglot is one who can speak six or more languages fluently. The term was coined by the linguist Richard Hudson in 2003 and derives from the word "polyglot", meaning one who can speak multiple languages.
