The palace stopped Suits from saying "poppycock" apparently

Korsh doesn’t remember how the palace got ahold of his scripts, nor does he remember who had to break the news about changes being made. (“Whoever it was, they didn’t like having to tell me any more than I liked having to hear it.”) He does, however, remember a specific instance in which the power of The Crown was wielded against him. The line of dialogue for Markle’s character was, “My family would say poppycock.” The royals nixed that term fast, “I presume because they didn’t want people cutting things together of her saying ‘cock.’ So, we had to change it to ‘bullshit’ instead of ‘poppycock,’ Korsh explains.

Korsh concedes that it’s initially pretty irritating to get notes on a script from anyone, not just Queen Elizabeth II, but he had a specific reason to be bummed this one got cut. “Poppycock” was an inside joke for his wife’s family, and “I did not like it because I’d told my in-laws that [poppycock] was going to be in the show.”

Even so, he ultimately understood why the royal decree was made. “[When] they explained it that way, and I’m pretty sure it got explained to me that it was about that [splicing potential], I had some sympathy because I wouldn’t want somebody doing that to her either. And the thing is, I didn’t think anybody really would, but also I don’t know. People are crazy.”
