Hey, Peter. Actually that kind of ironic use of language happens in English too. For example, if you want to wish "good luck" to someone in English, it is fairly common to say "break a leg". This sounds a bit like what you were talking about. Best, Paul

It is interesting to know but sounds really awful! What do you say to your enemies?

Probably you're looking for this word "banter"? Oh please not again, Jimmy and Tommy started bantering when peeing as I walked in. We enjoyed banter, vodka and filming on our train home. I doubt whether many native speakers know or use it much though. Haha sure I know what you mean. So it's like "Mate, you're not dead yet!" for "Good day, mate!" Can be applied amongst those who are real tight of course :)

It might be construed as a "Double Entendre" [from the French]. Here's s Wikipedia article on the subject. http://en.wikipedia.org/wiki/Double_entendre

There are some people I have a love/hate relationship with and I would say things I wouldn't say to my parents. Saying I hope you get hit by a car is a bit extreme though! If it makes your friend laugh then I guess that's cool.
