An after darker is someone who only listens or knows the song "After Dark" by Mr.Kitty, and or only cares about "After Dark" and doesn't check out his other songs. Actual fans of Mr.Kitty who like After Dark are NOT after darkers.

(originally coined by me in 2020)
Person 1: "Are you a Mr.Kitty fan?"
Person 2: "Yeah! My favorite song is After Dark!"
Person 1: "..Do you know any of his other songs?"
Person 2: "No, I don't."
Person 1: "Bro, you're an after darker. You're not a real fan."
