質問: I have to ask, when you kick a Japanese boy in the nuts or whatever, ignoring the obvious sounds a human makes when entering into such a state, what bits of language will they impulsively shout in their anger. I ask this as in English we have a beautiful array of anglo saxon gems to choose from, but in Japanese what is the equivalent?
回答: The best equivalent to F*** would probably be "kuso".(which means s***). But if you kick someone down there they probably will say "konoyaro" or "onore" to you.(which can be interpreted as "you son of a *****").
