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)
