Doyjaaan

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)

What the 23rd president of the united states says when he joins a cross country horse race and encounters an Italian monk and a crippled teenager with spinning nails so you team up with a dinosaur mans that can stop time to beat them to Jesus's heart so you can implant it in a random ass 14 year old woman to make a wall of yellow piss beams that defies gravity.
