Suckiness 

What the other poster said, except that "suckiness" is clearly a noun, not an adjective. Like "kindness" or "carelessness".

Sicknesses 

Multiple instances of sickness, simultaneously.

Devan came over to visit one day and surprised me with really great Jamaican Beef Patties. I already had a surprise up my sleeve with having Boodhoo's Jerk readily available. Both of these instances can be described as Sicknesses.

U.D. Editor Sickness 

The feeling you get after making too many decisions and reading stupid definitions on the U.D. as an urban dictioary editor. Mostly the U.D. Editor Sickness gives you a stomach ache, head ache, and your feet get cold and sweaty. Sometimes you feel tired and your mouth tastes like stale Doritos. Could be cured by listening to "Down with the Sickness" by Disturbed and drinking water.

guy: "Last night I made 1,000 decisions on the U.D., then I threw up"

Dude: "Sounds like you got U.D. Editor Sickness. Listen to Disturbed and drink some liquids, man!"

Turtle sickness is a result of sleeping too much or not getting out of bed until 2:00 or 3:00 pm. It is the feeling of still being tired even if you've slept for 10 or 12 hours. Your behavior and brain functions are noticably slowed down and reactionary time is also deminished.

She just woke up and she still looks tired - she must have turtle sickness.
