In Russian folklore. A big, stupid, hairy, unibrowed, asexual creature that roamed the forests of Russia and Canada looking for a mate. Legend has it that if the chornyvolk ever mated "the snows will melt off the great Siberian plains and mother Russia will drown". The Volga river is said to be "fueled by the tears of the chornyvolk because he cannot find a mate".
That guy is dumber than a Chornyvolk!
He may not be good with the ladies, but he's had more sex than a chornyvolk.
