:I see, from the indentation and the content of their responses, that , , and  appear not to have read the expert opinion I sourced, above. The literal meaning of words does not guarantee an adequate translation, especially in matters of emotion such as swearing. Our article on Italian profanity is indicative but not comprehensive. Urban Dictionary is not a reliable source. (See Identifying reliable sources: "...self-published media—whether books, newsletters, personal websites, open wikis, blogs, personal pages on social networking sites, Internet forum postings, or tweets—are largely not acceptable. This includes any website whose content is largely user-generated, including the Internet Movie Database, Cracked.com, CBDB.com, collaboratively created websites such as wikis, and so forth....") And I do not understand what is meant by "an impassioned reference such as an encyclopedia". I prefer my reference sources to be as dispassionate as possible, unless they are making an impassioned plea against internet censorship. Inasmuch as the expression "Vada a bordo, cazzo!" is worthy of inclusion in this article, it deserves to be translated for the convenience of our readers. And inasmuch as it needs to be translated, we owe them a duty to provide the best translation possible. I suggest this is accomplished by consulting the expert linguist (linguist: someone who studies how language functions  not just a speaker of multiple languages) whose piece I sourced above. I will quote from Bob Ladd, above, for those unable to click through. Dr Ladd is professor emiritus of linguistics at the University of Edinburgh (source) 
 :I know you really want to know about those swear words. The one that comes up repeatedly in the phone call is cazzo, which is probably the most common taboo word for "penis". In its literal meaning, a good English translation is probably prick. But it's widely used for generalized swearing, to mean something like For God's sake! or Bloody hell! In one of the most quoted parts of the conversation (you can already buy a T-shirt with this phrase on it), De Falco says Vada a bordo, cazzo! In one of the English translations of the transcript, this is rendered as Go on board, (expletive)! But De Falco is not saying Go on board, you prick!, as that translation might suggest. A much more natural way to render what he says would be Get the fuck on board! 
 :I will make the change accordingly.
