As an American, if someone made the equivalent mistake in English (“I want to eat cock”—that is, male chicken), I would expect the same sort of reaction to occur. Nobody would take it as a literal request, absent some very specific context clues.

The problem for OP is that the dad may be sensitive to this sort of thing because it is actually possible that OP meant what he said—it’s not like it’s unheard of for someone to mention a celebrity and someone else to bring up that celebrity’s problematic or criminal history. And the dad wouldn’t necessarily have put together it was a translation issue.
