Jan-go

Jan has a peculiar way of speaking, using onomatopoeia-like words to describe things and his emotions. Some are common Japanese onomatopoeic or mimetic terms, such as "mera mera" (the sound of flaming up), or corruptions of words or phrases like "seisei doudou" (fair and square) becoming "sei-sei de dou-dou". Japanese fans refer to his vocabulary as "Jan-go" (ジャン語).
