An expression I created for when someone spoils the plot/climax of a movie/show etc. I was looking forward to seeing. This is a reference to a Simpsons episode where Homer walked out of a Theatre after watching a Star Wars film. He is talking to Marge about how shocked he was that Darth Vader is Luke Skywalker's father. Thus, ruining the movie for all those within earshot.
"Hey, I saw this awesome movie yesterday man, this is what happens..." "COME ON! I want to see it, don't Darth Vader it for me"

"I wanted to see that new movie out, but John pulled a Darth Vader so I'm not interested now"

"Tim is mad at me still, I accidentally Darth Vader'd that movie he wanted to see"

The human male's generative organ. This modern term for the penis is due to the tool in question's marked resemblance to the principal miscreant in the Star Wars movies of the late seventies and early eighties. Except pink.
Han Solo wrestling with the Pink Darth Vader is an extremely well constructed euphemistic term for male masturbation.

Person 2: "Yeah, I'm surprised. He's usually a twat. It's giving me major Darth Vader Syndrome vibes."
