When you poop into the belly button of someone with a Herina.
"Dude! What the fuck is that?"
"That's my Dan Dan, man."
Something that was very impressive but ultimately down to luck and very unlikely to happen.
"wow, that was a proper Dan-Dan, I can't believe you managed to cheese that 250k high score David"
Very sus, very clean, ultimate golden sombrero
See 'Shake my head', or 'smh'; When one would witness or take part in an embarrassing situation where instead of shaking one's head, one would instead say "Shake my Dan" or "smd" due to Dan being a goddamn moron.
Wtf, they have 3 krakens and a laggy e-liter? "Shake my Dan.."
Dan: "I'm in the VC y'know."
