Polasek is a name given to a body builder teacher, usually who speaks French. They will have large muscles, which are never hairy, because of the fact they are waxed on a weekly basis. Polasek's will also tend to have a large amount of facial hair, usually referred to as ferrets, growing on their faces. They also tend to fail children, and give the classic smirk, which has been dubbed The Polasek Smirk.
You: Who's your French teacher this year?
Friend: I got me a Polasek, man!
You: Oh my donc! Good luck!
