An uncontrollable urge by a goth vampire
blood-drinking junkie to continuously consume human
blood, often times of their equally lame mate. Their unquenchable thirst for
blood usually surpasses their willing victim's ability to reproduce blood.
Kenneth: "Dude, let's go play world of warcraft. My
mom's not home."
Chase: "I can't dude, I'm totally vampin out."
Allison: "I got the razor. Do you wanna come over?"
Kyle: "No
way. Last time you totally vamped out. I had to go to the emergency room."
