a gay man who is a total douche because he's so good at gay sex he turns other people gay like a vampire does when he bites you
gay + vampire = gaypire
my friend was straight until he encountered a gaypire. I had to bash him in the skull with a crowbar to save him. it's the only cure.
a wonderful creature of horror (vampire) that has been so horrifically gayified that they now sparkles. This is often cause by Mormon house wives being aloud to write novels.
"he is such a gaypire... he even sparkles in the sun"
