Killing Spree: 殺しまくること or 大虐殺

K~S would probably just be written K~S. The Japanese are very familiar with the roman alphabet and English words, etc, (even if they end up as Engrish most of the time). The closest way to write it in Japanese would be ケイ~エス, but it'd be pronounced KEI~ESU.

Let me open it in Fireflop.

You'll have to go to the menus and find View > Character Encoding > More Encodings > East Asian > Japanese (Shift_JIS). It's usually SHIFT-JIS, if that one doesn't work, you'll have to try the other two because there's no automatic/default one. Assuming you have no Japanese encoding, once you select it, your browser should automatically install it, and it only takes a minute or two.

i isn't installing pls help me
cuz on IE is ask's Windows CD

Then simply pop your windows CD into your computer

That's the first time I've heard it do that... encoding just to view the characters should automatically patch itself from the internet. You usually need the Windows CD to install the IME if you want to write in Japanese.

i can see japanese characters on my firefox when i use my laptop (on IE now. at the library)

you could try un-installing FireFox, and download the new one, FireFox 2.0 its what i use. download it straight from the Mozilla website. it may help ^_^

How would you say phrases like:

I Love You
Boyfriend
Girlfriend
Kiss me please
Hug Me please (lol yeah I say that with my bf)

I love you (light, romantic)
Daisuki desu
大好きです

I love you (deep affection)
Ai shiteru
愛してる

Boyfriend
Otokotomodachi or Kareshi
男友達 or　彼氏

Girlfriend
Onnatomodachi or Kanojo
女友達 or 彼女

Kiss me please
KISU shite kudasai
キスしてください

Hug me please
Dakishimete kudasai
抱き締めてください

hmm..
between "Onnatomodachi or Kanojo" and "Otokotomodachi or Kareshi", they use more Kanojo and Kareshi, right?
Because I've never heard "Otokotomodachi and Onnatomodachi" (it's literally translated.. o__o)

Yes, kareshi and kanojo are most popular. I think second is ボーイフレンド and ガールフレンド, but people usually don't like katakana equivalents for some reason, so I try to steer clear.

Onnatomodachi <~
Otokotomodachi <~

I like them because they're blanket, just like the English words. Like when we say "boyfriend", it could mean a relationship boyfriend or a friend that just happens to be a boy. XD But I don't know how popular the Japanese terms really are. I just know that they exist.

Btw if I want to say 'I love' like referring to an other person not 'you' do I also have to use 'desu' or not?

Just look at my signature and you'll get the picture

I don't think you have to. But I may be wrong. *shrug*

No, 'desu' is just a copula that happens to be used in the pattern for liking someone/something. It's untranslatable in this phrase.

THING ga (dai)suki desu = I like/love THING

It depends on how informal you want to be. You can leave 'desu' off, or you can change it to its informal version 'da'.
