PTKD 

A psychiatric disorder that arises from incessantly watching and reading about the Kardashians until you are reeling from the trauma and need professional help.

My grandmother was in a nursing home that always had reruns of the Kardashians on the TV in the group room and her PTKD landed her in an inpatient psych unit!

charcarodon pteryops giganticus 

The Tau Cetian relative of Charcarodon Megalodon (the ancient Great White Shark, specimens of which up to 100 feet in length have been found as fossils on Earth). The distinctive feature of the Tau Cetian variety, notwithstanding its length, is its winglike appendages (similar to those of terrestrial "flying fish" classification "excocetidae"). The Tau Cetian Great Whites are known to be able to fly lengths up to 400 meters, and exceed altitudes of 13 meters.

The lagoons of Tau Ceti were placid until the Charcarodon pteryops giganticus broke the surface of the water.

Ptoof 

The standard measurement for a fart as defined by the following:
A = Length of fart (seconds)
B = Volume of fart (decibels)
C = Smell of fart (scale from 1-10; must be measured by others, 10 being the smelliest)

Ptoof = A*B*C

NOTE: Minimum value for A, B and C is 1.0

Dude #1: Hey man, did you just fart?
Dude #2: I sure did, how did you know!?
Dude #1: Dude, it smells terrible!
Dude #2: Really? I think it smells awesome! How many ptoof's do you think it was?
Dude#1: Cough (leaves and comes back a few minutes later).....Well, I didn't hear it at all but it did smell terrible. Let me calculate this one for you.
A = 1 (inaudible)
B = 1 (inaudible)
C = 8.5 (smelled like someone ptoof'd in my mouth)

A*B*C = 1*1*8.5 = 8.5 ptoofs

Dude #1: Congrats on a 8.5 ptoof fart.
Dude #2: Hold on, I have another one. Be ready.

PTD 

Post THIMUN Depression, more commonly known as PTD, is a very serious condition. Although it sounds quite ridiculous, it is very common amongst young adults returning just returning from Den Haag, The Netherlands towards the end of January. Symptoms include:

1. Sleeping past 1 in the afternoon

2. Not wanting to go anywhere

3. Reminiscing by means of, but not limited to:

a. constantly looking at picutres from THIMUN

b. reading old MUNITYs

4. Constantly referring back to debate. For example:

a. Point of information to the chair

b. The chair would like to remind the House to speak in 3rd person

c. Point of personal priviledge!

If your loved ones have more than one of the aforementioned symptoms, he or she may be suffereing from PTD. The delegate of Tonga would like to urge the other delegates to push through these hard times and remember that there IS help.

THIMUN 2012 is on it's way.

Thank you Mr. President, have a nice day.

Delegate 1: Oh man, I can't believe THIMUN is over
Delegate 2: Me either. I miss it so much
Delegate 1: Sounds like you've got a case of PTD
