Luffy is the rubber powered captain of the Straw Hat Pirates in Eiichiro Oda's One Piece, which began as a manga in 1997 and as an anime in 1999. His optimistic, can do attitude has made short lines from the series popular as reaction sounds far beyond the show itself. Clips like this ok circulated on anime soundboards and in fan edits, where a familiar character voice can replace a plain text reply. It remains in use because One Piece is still widely watched and Luffy's voice is instantly recognisable to fans.
