Did the words ‘Millennium City’ make your follicles turn all futuristic
The phrase "Millennium City" has a very sci-fi, futuristic feeling to it. Here, turn means "become". "All" can mean "completely" or "extrememly". So the author is asking
Did the words ‘Millennium City’ make your follicles become completely futuristic.
I think he is trying to ask "Did those words make you that excited?" Something like that.
Wookiees (/ˈwʊkiːz/) are a fictional species of intelligent, hirsute bipeds from the planet Kashyyyk in the Star Wars universe. They first appeared in the 1977 film Star Wars Episode IV: A New Hope. The most notable Wookiee is Chewbacca, a companion of Han Solo.
This is an image of Chewbacca.
Species names are often capitalized.
The species Tyrannosaurus rex (rex meaning "king" in Latin), is one of the most well-represented of the large theropods.
Yes, it is a metaphor (not because of the capitalization). Presumably, his wife is not a Wookiee. Calling her a Wookiee is insulting since I doubt any woman wants to look like a Wookiee.
This, and the Millennium Falcon are references to Star Wars. It seems the city has been referred to the "Millennium City", but I don't know if "Millennium City" is also a reference to Star Wars.
