I've seen hundreds of anime. I couldn't wait for subs so I downloaded a raw. And I understood what they were saying. I've learned how to understand nihongo without even knowing it.
Looks like you don't need subs anymore. Congratulations you've graduated
Do you want a diploma? What dialect do you understand the Commie or gg dialect?
Subs come out rediculously fast nowadays, though. This explanation really only works if all you do is watch anime.
Just because you understand it when they say kawaii, daijoubu, baka and oniichan doesn't mean you understand Japanese.
Go watch hyouge mono without subs. That should shatter your delusions.
