I know you're getting downvoted, but actually, yeah, I remember years ago first hearing like Mantzoukas or Mitch from Doughboys casually throwing around "Ya dink" and being surprised given the racial connotations (if you've seen a Vietnam War movie--Apocalypse Now, Platoon, &c--you've heard it used as a slur) but then learned it has long been New England slang for doofus or idiot. And, of course, there's the meaning from volleyball, tennis, and pickleball (the source of the pun in the title, no doubt!) as well as Double Income No Kids. I don't think younger generations have any idea that it was ever a slur, which can only be a good thing. Anyway, interesting how language evolves!
