What's with the "x" in "Hunter x Hunter" (and other anime/manga)? I am wondering what the "x" in "Hunter x Hunter" means. To clarify: I am also talking about what the "x" means in general as many other anime/manga also have it in their titles.

A quick Google search for this question returns a Yahoo answer result which claims that the "x" is just for style and has no meaning whatsoever. Is this correct? Does this also apply to other anime?
I've done some searching about the names like this, and I wasn't able to find any particular explanation. Some people say it's just for style, other argue that the × is another form of "vs" (which kind of makes some sense), or "and" (like &amp;), or "with". (Not to mention that it might also mean "kisses" like in "xoxo" = "hugs and kisses", but that's most likely irrelevant :P)

It's worth noting that it is not uncommon to find odd letters in anime/manga titles (e.g. Lucky ☆ Star - らき☆すた has a star in the name) and even in character names (e.g. Black☆Star from Soul Eater has a star in his name as well). Also the 'x' in "Hunter × Hunter" is not actually the letter 'x', but rather the symbol ×.

So, considering the above, I would personally say that it's just for style.
