[Help] Japanese slang
 

I study japan in formal education for some times now, but still when I read manga and watch anime those knowledges is useless.

the thing is, Japanese slang is far different from formal Japan you get from the book.

so can anyone here sharing their experiences in speaking with daily japanese, probable with "slang" words. ^^

Are you sure it is slang? I would divide the language outside of textbooks in 3 classes (doesn't apply only to Japanese, but to all languages):
1_ Everyday language: it comes down to getting rid of extra fancy phrases and structures.
2_ Colloquial language: Here the language becomes more "personalized". Sounds become more simplified for a more practical use of the language, some shortened and some words linked (for example "wanna", "gonna", " 'sup" and so on).
3_ Slang: Slang is a real sub-language where words assume a completely different meaning from their original one or again new words are created. The use is usually restricted to a certain group of people (gang, young, some ethnics and so on). When the new words become popular they start being used also from people outside of the group.
(I left out the dialects, which are a big important class as well).

So are you sure you have problems with slang? I ask you that because I know that colloquialism is probably as hard as slang (at least for me).

Go take a hike, pal!

who are you to say what is and isn't a valid reason to learn something?

Just go read my other posts and see how I go out of my way to help members learn Japanese!

And what have you done for other members compared to me, seriously?

well in this case you're not being helpful; you're being abrasive and intolerant.

How do you help a dude who says he has learned formally but chooses to put BAKABAKABAKABAKABAKABAKA as his sig to show for it?

I have all the reasons to be intolerant with people who show no respect for my culture and language as you would with your counterparts.
