Someone who, when discussing their musical tastes, proceeds to list an unbelievably large amount of genres. Usually common with any type of Metal fans.
Person 1: "So what kind of music do you listen to?"

Person 2: "Well, i really like Black Metal, Death Metal, Thrash Metal, Grindcore, Hardcore, Progressive Metal, Folk Metal..."

Person 1:(Jeez, what a Genre Nerd...)
