I know... enough. >_>
I don't actually speak Japanese, I've just picked up a lot...
...that and I'm the type of weeb who has the Japanese Language support installed in his computer, I don't necessarily need it, I just like having it.
I'm familiar enough with Japanese that I can recognize individual syllables in the spoken language (unless they're talking super fast), even if I don't actually know what they're saying (which is "pretty often"). Similarly I can "read" Japanese when it's written in Katakana and Hiragana, I only recognize a handful of Kanji and need
Furigana (the text that they put above/next to the Kanji to enable kids to understand them) to read them.
