In
Japanese, "dojyaaan" basically means ta-
da.
This word has achieved "meme" status (in the
JoJo's Bizarre Adventure community) due to the character Funny Valentine's habit of saying "dojyaaan".
*Funny Valentine uses his
stand, Dirty Deeds Done Dirt Cheap, to hop between dimensions*
"DOJYAAA~~N!"
(once again, dojyaaan means
ta-
da)
