Commonly inferred as a metrosexual (or, in some cases, sexually confused) vampire, the term is more popularly linked to Edward Cullen from the Twilight Series. Meaning, glampires are inherently gay and drive stakes through their asses.
Blade: What the fuck, vampires aren't supposed to SPARKLE!
Edward: Oh no honey, I'm a glampire. I rock the glitter and it's FABULOUS. I don't bite my victims, but I do recommend tasteful color schemes for their homes, as well as feng shui tips.
