Fun game for ladies: In front of a geeky dude, say “Silence, Earthling! My name is Darth Vader! I am an extraterrestrial from the planet Vulcan!”
If he gets all mad, condescendingly explains to you why you’re wrong, or starts talking about that “fake geek girl” nonsense, not only do you know that you should stay far, far away from him, but you also get to tell him he’s one to talk about people not having enough nerd cred
Because you just watched a “Back to the Future” reference fly straight over his head
