I was watching the anime かんなぎ, and heard the following line:
男はみんな[狼]{おおかみ}だわ!
"Men are all wolves!"
I was curious as to what it means to call someone a "wolf", so looked 狼 up in Daijisen and it came up with "someone who feigns being gentle, but in reality is a terrifying person" in the 2nd definition.
But why exactly did 狼 come to have this connotation? Does it have similar origins to the English phrase "a wolf in sheep's clothing"? Or something else?
