John ratted me out, so I got into trouble.

John ratted on me, so I got into trouble.

Do both rat on and rat out mean revealing somone's secret? Are there any difference?

    They mean pretty much the same thing: to inform police about someone's involvement in a crime for example; Always with the intention of betraying someone. :)
