Where did the whole "Braaaaiinns" thing start with zombies?

Where did the whole "Braaaaiinns" thing start with zombies? It's not in any Romero but it's somehow linked to the whole zombie culture.

 

This seems to be the rare case where it actually happened (unlike “You dirty rat”)

 

And the wording is also correct (unlike “Play it again, Sam” or “Luke, I am your father”)

 

Yes, it appears the source is “Return of the Living Dead”!

[Trouble]

This is a strange question for someone who has lived and breathed theatre for years, so please don't judge.

Why is the Shakespearean "scottish play" bad luck? I mean, you can't even say its' name in a theatre without having to exorcise in some silly way! I've tried looking it up, but the answers are unsatisfactory. And the people I work with (who would actually know) refuse to talk about it.

I have a show coming up in a month or so and I didn't want to mention the name (just in case). Could you enlighten me?
