Sometimes in songs or poetry we are set-up to expect a rhyming word but instead another word is supplied. An example is the Killers song *Mr Brightside*:

> 
> *Now they're going to bed.  
> 
>  And my stomach is sick.  
> 
>  And it's all in my head.  
> 
>  But she's touching his chest*
> 
> 
> 

To my recollection I've heard these called several different things in the distant past.

So what are these anticipated but missing rhymes (or the works that contain them) called?
