Is there a more casual way of saying "beyond reproach, criticism"?

Question

Is there a more casual way of saying "beyond reproach, criticism"? When I hear "beyond reproach", I find it that it sounds way too formal, and not too informal enough. It sounds like something a British actor would say, but it doesn't sound great if you speak with friends. Is there a way more casual way of putting it?

Answer 1

(All definitions below are from Merriam-Webster's Dictionary.)

For starters, there's irreproachable:

not reproachable : BLAMELESS, IMPECCABLE

There's also unimpeachable:

: not impeachable: such as

: reliable beyond a doubt

: not liable to accusation

If those are still too formal, perhaps untouchable:

: exempt from criticism or control
