The latest thing may be teens having a "Vampire Party" with no parents around and a house in the dark to welcome them. It also may be the source of the new outbreak of cases of aids or HIV positive visits to their doctors.
The 'Parties' are usually created from the latest Twilight, Vampire Diaries and bestselling books on vampires.
"I know it sounds harmless", stated a leading medical authority, one Thomas Caspar, MD but the cases have even been discussed on Oprah by Doctor Oz.
"These teens watch all the Twilight movies and others and there's this sex thing about the whole situation", stated Doctor Caspar. "But serious bites can go beyond hickeys and lead to bleeding that can lead to diseases being passed from one teen to another."
Police in many major cities have also reported cases where they have had to raid parties after some teens have been attacked at the dark, candle-lit homes.
"Actually, when we have raided a place after a telephone call, we have found some older gents disguised at the party, sometimes he's also the actual owner of the house and began the Vampire Party in the first place", stated one member of the vice squad in Seattle.
"It's not the neck biting that's passing on these diseases. It's what the neck-biting is leading up to."
