In the No Doubt song Oi to the World are the following [words](http://www.metrolyrics.com/oi-to-the-world-lyrics-no-doubt.html) spoken:

> 
> He'd say "Oi to the punks and Oi to the skins
> 
> 
> But Oi to the world and everybody wins"
> 
> 
> 

So what does the phrase mean? It seems to mean "screw them" in the first 2 instances, but that doesn't fit in with the last one.
