[Hatredcopter]

Roughly translates to:

"Even though I can't read or write Japanese, things that are written in Japanese are cooler, so my younger brother translated [this] for me."

Just as a side note, I believe 通訳(tsuuyaku) refers to oral interpretation only, and not written translations, so that choice of word might have been a mistake for whoever made this image. Maybe a native speaker can clarify whether I'm correct on that...
