If Home Page Do Nothing, If All Else Show This Content

It sounds like you’re looking for:

if ( ! is_home() && ! is_front_page() )
{
   // the stuff you don't want to show on the front/home page
}

where we use that ! ( A || B ) = ! A && ! B.

But it also depends where in the theme you are using the code snippet.
