History -

The term originates from one of history's greatest serial rapists - Donkey Kong (who was in fact a Silverback gorilla). What distinguished this rapist from an everyday boring rapist was his fearsome signature move, dubbed the "Donkey Punch".

In the aftermath of his trial and conviction, psychologist and author Dr. Mario coined the term in his best-selling novel, "Rogue Silverback : A True Story Of Fear, Love, And Anal Rape".
Fliers on campus warned students not to travel alone at night, lest they encounter the dreaded Rogue Silverback.
