If there is, we don't know what it would be. 

Is there any difference between "arsehole" and "dickhead", or "damn it" and "bloody hell"?  Not that I know of. They are just words and phrases used to insult or show annoyance/frustration/pain/etc. 

What about in Greek? I'm sure there are words that you use as insults to people that aren't taken to mean what the word(s) might literally mean. :)
