Bisexual, Vampire Teen Wizards 

AKA, BVTW Syndrome.
The most common example, is My Immortal, which is considered to be the worst fanfiction ever produced and, may have in fact, existed since the dawn of time. Some believe it to be one of Nyarlathotep's 999 forms.
It is also commonplace on free form roleplaying message boards.

The disturbingly common practice of writing Harry Potter-based fanfiction or creating HP-based characters that are, for purposes of the female writer's fantasy, bisexual for other "hawt Hogwarts guys" and, on occasion, situationally "hawt" for the writer's alter ego, female main character.

...Oh and they're also VAMPIRES.

Bad HP slash writers (oxymoron?) LOVE vampires.

People who suffer from BVTW Syndrome:

-Likes-
Vampires
Any combination of: Ron, Harry, Draco and Snape fucking in the Forbidden Forest.
Goth anything
Hot Topic
F-bomb dropping Dumbledore
Gun toting Voldemorts

-Dislikes-
Spelling
Hogwart's boarding school Dress Code.
Vampires that have fangs and burn in sunlight.
Magic classes.
Quidditch
Writing anything with even the remotest of semblance, to the characters and stories that these fanfics are based on.

Bisexual, Vampire Teen Wizards are why a Harry Potter role playing game will most likely never see print.

Fo'Teen

An exclamation you yell at a girl when you think she is purposely dressing much older than she really is. It's a warning signal to other guys who may be foolish enough to try to tap that ass. Also known as jail bait.

Jack and Rich are staring at this scantily clad girl across the way. She has a young face, but is dressed like a prostitute. Bernard comes to their rescue.

Bernard: Dude, what the fuck are you doing checking out that young'n? Shes Fo'TEEN!!
Jack & Rich: Oh shit!
Slutty girl: Hey, fuck all of you!

American teen 

Stupid, ignorant person who doesn't know a thing about the rest of the world.
Thinks the USA is the best and only civilized country in the world. Doesn't know geography or any other language than English (they can't even spell correct in English).
An American teen can't think without categorizing everything. He/she cannot think outside of the box. They absolutely need to be part of some kind of group: emo's, indie kids, scenesters, valley girls. They make EVERYTHING mainstream.
Think they are really cool and 'different' when they 'go backpacking through Europe' for the summer.
They're highly uneducated.

American teen:
Is Belgium a part of Germany?
Isn't Europe, like, full of small countries and cathedrals?

European person:
you're stupid. I know tons of things about your country AND I speak your language and haven't got a clue about Europe?!

Pre teen 

A person that is misunderstood for a preppy little cheerleader who secretly loves disney channel. I'm a pre- teen, totally mellow and love Green Day, Nirvana, and skateboarding. So?! I wear lip gloss, my younger friend wears eye liner. By the way, we could spend over 2 hours trashing Justin Beiber, Miley Cyrus, etc... I am not a abercombie and fitch shopper, I am not what you think I am! I'm told by many people I have the independence, look of a teen. Someone who I walked pass was like: "She looks likes she's actually 17 except height and puberty stuff." (Not exact words, that's be weird).

Teenager: Look at that little pre teen listening to her Selena Gomez on her fancy little iPod her parents had to buy.

*12 year old listening to Come as You Are, worrying about all the money she wasted buying her iPod that took 3 years to pay for, walks down the street*

16 year old: Look wearing lip gloss, but probably worships Miley Cyrus

*12 year old goes on her phone to her blog trashing disney channel celebs*

Normal Person: Look at that awesome maturity, and teenager personality she has.
Normal Person's Friend: I know right?!

Dirty Teen Mustache 

A Dirty Teen Mustache is a mustache that some teenagers thinks looks cool on them, but it doesn't. It's like the kid isn't meant to have a mustache, but he has one anyway. That's called a dirty teen mustache.

bawb: Hey, what's up with the mustache?
John: Oh, right, how's it look :D.
bawb: uh, no. Shave that Dirty Teen Mustache off.
