[Q]: Question: Sometimes people are referring to mechanical objects as "she": I love my car. She always gets the best service. Are there any rules when it is appropriate to use "she" instead of it, and is "he" ever used in such context?
Answer: The pronoun "she" is sometimes used to refer to things which can contain people such as countries, ships, or vehicles, or when referring to certain other machines. This, however, is considered a stylistically marked, optional figure of speech. This usage is furthermore in decline and advised against by most journalistic style guides such as the Chicago Manual of Style.[9] If used, the terms she, her, and hers are always used, regardless of the entity's name - for example, "The U.S.S. John F. Kennedy (CVA-67) was laid down October 22, 1964. She was launched on April 1, 1967..." "He" in reference to an inanimate object has not, as far as I'm aware, ever been common usage in English.
[A]: yes

[Q]: Question: Is the word "dude" becoming gender neutral? I don't think so, however, has modern usage changed? Are there some recent examples of "dude" being used to refer to a woman or group of women?
Answer: Personally I would feel quite creeped out if a male individual would address me with dude and I have not seen the word dude used as a gender neutral term. If a female individual would address me with dude I think she could get away with it, but it's not something I have actually seen. A (female) friend of mine does use the terms dudette dudette (plural dudettes) (slang, often humorous) Term of address for a woman. (slang, often humorous) A cool woman, especially a surfer or skater. [...] and dudess dudess (plural dudesses) A female dude, i.e. a cool female. Although as stated this usage is often a bit joking and humours rather than serious. For that matter, it can also be pointed out that dude is still only defined as a male term in the dictionary I checked.
[A]: no

[Q]: Question: I want to ask whether I can use the word "Fuck" in a formal context. Apparently, the word dates back to the early 16th century, so it shouldn't be considered slang (although, it is misused as slang for other reasons), but regardless of its vulgarity, could I use it in a formal context with its original definition? I imagine that people will be surprised, but when realizing in what context I am using it in, then it will be more understandable and acceptable to use it. Firstly, I do not even know the definition of the word due to its vastness in meaning, I always thought it was an exclamation-like word meaning nothing (for it to mean sexual activities is a slang definition, is that not correct?), but used purely for emphasis. What does it first and foremost mean in its original/accurate and/or formal definition? I also know of another definition of the word "Fuck," which is "I will fuck you" as in "I will defeat you" (in context of fighting or combat), is that a formal definition as well? I mainly ask for this, because I need to use the word in this context, specifically and especially. Also, side question, is it possible not to always make it a vulgar word? Thanks in advance.
Answer: It is very unwise to use "fuck" in any formal context whatsover (outside of technical discussion of language). The word either has strong and forceful sexual meaning, or it has the debased banality of over-frequent use by those groups of society who lack nuances and who express themselves repetitively and coarsely. In neither case does the usage fit with formal discourse. In short, although an excellent word to describe a very pleasant and necessary activity, it is rude.
