Which is a good defensive opening move which allows for a quick castling?

There's no way of White castling faster than Black if Black plays correctly...

lol! And in the next move, the king goes rampage, capturing the remaining 15 pieces ahhahaha :D

oh pardon me, the Black king flew off to Miami before the White king came knocking :P

This must be checkers with Flying Kings-lol

ahahahahah n1 paceman :D

I would say Antoshin's  Variation of the Philidor Defense. It is both solid and sound, but it's also very interesting and can even lead to a tactical game if you want it to. 

So, that opening basically works in the favor of White?

What do you mean? I don't see where you get that idea?
Perhaps when I wrote about "equalizing" it gave the wrong impression. No, that is a solid variation for Black and perfectly playable. I recently bought The Philidor Files which is a book on that opening written by GM  Christian Bauer, and the analysis seems to indicate it is perfectly playable. I've had good experience with it as well. White often underestimates it.

you can also fake a fools mate attack!

lol I think you meant "fake a Scholar's Mate" attack :)

yah... oops on my words!

after rh1 you can move the pawn to h5

can you post a diagram showing how it is done? i don't know crap about names of oppenings...
