The phrase "no way" is similar to [this question about the expression "you wish!"](https://spanish.stackexchange.com/questions/172/how-to-translate-the-idiomatic-expressions-i-wish-and-you-wish) but is perhaps more of an expression of disbelief or rejection of what the other speaker says (short for There is no way that just happened!). It also can be friendly enough to be used jokingly or teasingly, like when another person says "Yes way" back and you say "no way!" again (like "nuh uh" / "uh huh").

I think I have heard just *que no* used - for example, perhaps something like this:

> 
> A: Cuando llegué a casa, el perro habia comido mi tarea.  
> 
>  B: Que no!
> 
> 
> 

[This discussion on "a que sí" o "a que no"](http://forum.wordreference.com/showthread.php?t=110254), like some others I found while searching, makes it seem like "a que no" is the way this might be said, so maybe I haven't heard the "a":

Is *que no!* a good translation of *no way!* or is there a better one?
