blackberry freeze 

the situation that occurs when someone is participating in another activity (exe. walking, talking, working out, etc.) and realizes that they have email, facebook notifications, etc. on their blackberry, and is forced to stop their current activity and respond to multiple forms of communication on their blackberry before returning to their original task.

Look at that idiot stopped in the crosswalk, he pulled out his blackberry, saw his messages, and now is stuck in a blackberry freeze right in the middle of the street.

Black Hairy Tongue 

1. A benign (but disgusting) bacterial growth in the mouth that causes the tongue to become black and fuzzy. May spread to the teeth.

2. The grossest thing ever.

3. The side effect listed on the back of Pepto-Bismol packaging as "a harmless darkening of the tongue."

4. The #1 reason to never take Pepto-Bismol.

You: I woke up this morning with Black Hairy Tongue.
Friend: Ew. You shouldn't have taken pepto before bed!

Black-flakking 

Black-flakking is the the act of tricking others into opening a link to the much talked about music video "Friday" by Rebecca Black. This trick is very similar to rickrolling. To be Black-flakked is to be the victim and the act of Black-flakking is done by the predator/troll. The prank is considered to be funny because the song is horrible in many, many ways.

Troll: Hey, dude, you should really check out this video! It's super hilarious and has monkeys!
(secretly sends link to "Friday" because they are
Black-flakking)
Victim: Okay!
(opens link)
Victim: WTF?! That was the worst music I've ever heard!
Troll: You just got black-flakked! U mad, bro?

Black-Fridayed 

To be mobbed or overrun by an onward surge of crazed shoppers/zombies - possibly resulting in grave or serious bodily harm.

Schlomo: My goodness, Saul, why are you in a wheelchair?
Saul: Well Schlomo, I was standing first-in-line for the special midnight Walmart opening to buy the Collector's Edition of Trailer Park Barbie. When doors swung open, I was suddenly "Black-Fridayed" down the aisle by rushing crowd of crazed little old ladies and overweight fat leg-ged women with 2 children in tow. Being overrun, I fell to floor and was stepped on, trampled at, and treated like dirt. SO! Lesson is: Never be first in line at a Black Friday sale!
Shlomo: Oh, didja get the Barbie?
Saul: ... ... ... Thanks fer askin' ...

Person 1: Hey, are you going to (insert store here) for Black Friday shopping?
Person 2: Heck no, I'm shopping online. Don't want to be trampled to death by someone carrying a large, cheap tv.

Black and Forth 

When you go black, but then you go back.

The saying "once you go black you never go back" is not true. My sister Alison has gone black and forth many times.
