I don't really see those things a jokes. The groups I play Settlers of Catan with tend to call lumber, grain and ore "wood, wheat, and rock", but no one thinks it's funny, it's just what we say. I mean, calling Curses "purples" isn't a joke, it's just slang.
"Dookie" is, well, a little different but it's never annoyed me. If it is a joke, it is probably an inside joke, which makes it significantly less funny for your audience, but it isn't confusing like calling VP Tokens "Dukes".
The WW thing, I guess I see that as an homage, not a joke. I mean, A Dominion card came out that happens to share the first half its name with one of the first guys to make Dominion Youtube videos, who also happens to be one of the best players in the world. It doesn't seem like an odd thing to me, but if the man himself isn't fond of it that is something to consider.
