That's already pretty specific.
"Yea I want a Dutch accent from the North West of Belgium, but not too far North West, because that doesn't sound good" (Lol, just having fun with exaggerating

)
I know, but the way we pronouce R's is hilarious.
"I think I'll pahk my cah ovah there, achrass the street."
Stretch out your R's, throw in every minor swear word you know (make several up for good measure), and
BAM, you have a Bostonian accent. It'd fit perfectly in Brink!
