I've actually given some thought to whether coasters are more masculine or feminine. I've always considered Millennium to be female, and Maverick to be male. The strange think about me is that I feel like Griffon's male but SheiKra's female, ad for some reason I see most B&M's bar SheiKra and Banshee as male, though Leviathan might be female.
I guess I just base it off of how it looks and runs. Millennium is purple and silver and has a pretty graceful layout, while, say, Volcano: The Blast Coaster looks like a big mountain with twisty girders sticking out of it ad looks really threatening and while cool, not pretty.
Theme plays a huge role in it too. While Wild Eagle runs and looks like a female coaster, I feel like those eagles are male. Same with GateKeeper. It's real and white, but those gargoyles are male, I'm sorry. And while Raptor is blue and green and runs very aggressively and roars, it's another one of few B&Ms I see as female. I don't know if it's because of the pink on the trains but I see it as momma bird.
This one I'm not sure of. The color scheme makes me want to say female but in my eyes all of the wing coasters bar Flying Over the Rainforest are male. If the trains are bat-themed as the teasers suggest than it's definitely male.
Here comes the hate for actually have thought of this before. XD Though I get so excited about coasters that people have jokes with me using the same "coastersexual" posted a few posts back. And you may see these rides differently than I do, I might be weird, I don't know. XD
