Chosen answer: It's a more complicated question than you might think. Two versions of the scene were filmed, the main one, where Roy says "fucker" and an alternate, originally intended for use on television, where he says "father." Different versions of the movie use different takes. Of the three best known variants, the original theatrical release and the inaccurately-named Director's Cut both use the "fucker" line, whereas the Final Cut, the only one that Ridley Scott had full control over, uses the "father" line. What he's saying will depend on which version of the movie you were watching. Only you can answer that one.

Chosen answer: It's simply a term used for the police detectives who specialise in tracking down and "retiring" replicants. The origin of the phrase is not given in the movie. In reality, Hampton Fancher, who wrote the first draft of the script, encountered the term as the title of a movie that was never made, that centred around a supplier of illegal medical equipment. He and Ridley Scott liked the phrase so much that they acquired the rights to use it for their movie.

Chosen answer: It measures a number of involuntary physical responses, like heart-rate, breathing, eye movement and pupil dilation in response to questions designed to provoke an emotional response. By examining the intensity of these responses over a series of different questions, the subject's empathy and emotional response levels can be measured, allowing those running the test to determine the true nature of the test subject.

Answer: There doesn't appear to be any evidence for that. The names are vaguely similar, but, other than that, there's nothing to link the two.

Answer: Why shouldn't he? Just because he speaks English, it doesn't automatically mean that he must therefore bow to the linguistic preferences of others and use it. Many people take pride in their native tongues and prefer to use it. And if it puts Deckard at some small disadvantage in the haggling, so much the better.

Answer: The two most notable hints are as follows. The first (which is only in the Director's Cut) is that after Deckard dreams of a unicorn, Graf makes an origami unicorn and leaves it at Deckard's apartment. Some people interpret this as suggesting that they're aware of the memories that have been given to Deckard to prevent him realising his true nature. The second hint is that replicant eyes glow in certain lights - at one point in the film, Deckard's eyes can be seen glowing in the same fashion. Ridley Scott has stated on several occasions that, as far as he's concerned, Deckard is a replicant, but he does concede that they deliberately left it as somewhat ambiguous - the viewer should decide for themselves.

Answer: Rachel asks Decker at one point if he had ever taken the replicant test himself, and he doesn't answer. Even though the movie itself doesn't seem to stress the point, in the book on which the movie is based "Do androids Dream of Electric Sheep?", the question of whether the protagonist detective is an android is the main theme.
