Get the GET YOUR DUCK SICKmug. A man or woman with an illness that dates a normal healthy person. People with low self worth will look at a "sick puppy" and see that them as cute, needy, and feel attracted because they believe they can fix or comfort the person and find purpose for their own life. It's also a way to escape rejection or being dumped, because it's hard to get dumped when the sick puppy dies.
Since his divorce Larry likes to chase sick puppies. He wants to fix them to make himself feel important. He found a sick puppy in England, traveled to her, and porked with her while she was in hospice.

Get the sick puppymug. When you're so hyped up on coffee your body starts rejecting it. It can be confused with the flu if you've been around people who've had it (if you got your immunization shots then this would rule it out)
One moment: OMG IM CAFFINATED I HAD TO CUPS OF COFFEE
The next moment you're rushing to the bathroom holding your stomach for dear life,
"Damn it (ughplr) I'm coffee sick again

Get the coffee sickmug. 
This is also an old or possibly ancient nautical term used to describe the condition in which a sailor falls in love with ocean going life or even the sea itself. One with this condition may spend several years upon the waters with only brief time ashore.
I can't believe Hugh turned 62 today and he already has 37 years seatime(1 year seatime =365 days at sea) he must have been young when he got the sickness.

Get the The Sicknessmug. When one sick individual in a couple just can't keep his/her mouth off their gf/bf/fuckbuddy, passing on the virus that they will eventually get back from said gf/bf/other, creating a vicious tennis-like volley of sickness. The world must know.
