Let me just say that a commun word used by today's Polish youngsters to describe something "awesome" or "cool" would be
Zajebisty
(Zah-yeb-ee-sti)
But you probably won't find it in any dictionary because it is more of a slang term.
But a more traditional word for awesome would be:
STRASZLIWY;  PRZERAZLIWY

just thought I'd clear that up. It souds a lot better than odkuzacz...
