vamping out 

Isolating oneself with or without drugs/alcohol.

John: "What do you plan to do with your vacation days this year?"
Dave: "Idk, I might golf a little but after months on the grind I'd really rather just buy an ounce and vamp out."

Later that day...

Jaon: "Do you know what Dave's doing for holiday?"
John: "He says he's vamping out... Lucky prick. Wish I had gotten a vasectomy too."

vampin out

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."
