I was watching this clip on youtube of One Piece (a rather funny one) and the translation of what Luffy says is "They have been grabbed!", but I'm not able to figure out exactly what he says in Japanese. It sounds like he says "niigata" but I google this and it doesn't find anything related to what the translated text shows.
rcdailey9335-san, I'm sorry, but I have no idea. I listened to it several times now and tried to understand the story too, but it doesn't make sense. It sounded like "nigeta" (= someone escaped) but this totally doesn't make sense. I'm not following this manga, but it could be some special expression this person uses in the manga which is a created language, not real.
