Db
Diarrhea Bubble. There are 5 different classes of pure, 100% Db's.
CLASS ONE-
The regular Diarrhea Bubble that someone gets occasionally by eating something that doesn’t ‘mix’ well with his or her stomach.
CLASS TWO
A little more intense, with semi squirts of pure liquid that sting’s on the way out.
(Note: class’s three, four, and five cannot be considered if the Db were taken in a nice toilet)
CLASS THREE
This is strong Diarrhea that can’t wait more then a half an hour. even if this includes a public bathroom.(not including a school bathroom)
CLASS FOUR
This is extremely strong Diarrhea that has only 5 minutes until shit MUST exit. This does include a school bathroom.
CLASS FIVE.
I have only known one person that has gotten a pure, sober, class five Db. I was there first hand and can tell you the incident laid upon him. Jacob was swimming in the ocean when a class five hit him, He later told me it felt like “A tone of bricks had hit my stomach.” With what he thought he had on his hands was a class four, he thought he could make it to the hotel room. As he ran less then 50 feet to the public shower’s to walk up the stairs to our hotel room, it hit him. The class four had turned five. He had no other choice but to bend down and shoot the Db in the wide-open shower, with the janitor wathing, there was nothing to do aftwrd but walk out with you head held low.. These kind of Db’s are rare but do happen. There are no warning signs and can’t be contained after one minute. They are extremely painfull and often end up leaving you with no dignity and no feeling of your ass.
--- Now there are Classes six, seven, eight , nine and ten’s. But these classes fall in the categories as “non-pure” Db. They are class four and five’s mixed with either or all headache, back pain, dizziness, throwing up, etc.. A class six would be maybe a really bad hangover with a pure class five. A class nine would have to involve spectators, throwing up, headache and a pure class five. A class, ten is your final Db. It’s the final 21-gram’s that leave your asshole as you die. No one has ever survived it.

dB
A decibel - the most awesome thing in the world.

Contrary to popular opinion, the decibel is not exactly a pure measurement. It is a multiple - amplifying a sound by two decibels multiplies the frequency volume twice over, amplifying it by seven or more may blow your speakers, unless you have kickass speakers. On the other hand, putting the amplification to a negative number will reduce that frequency by the multiple.

Adding decibel amplification usually comes in the form of a number with a + for adding amplification or a - for reducing it.
Guy 1 - "Dude I just put up the speakers to around +15 dB!!!"
Owner of Speakers - "OH SHIT!"
