T.A.D 

TAD. Also known as 'Thanos Ass Disease' is a disease that can be caught by hanging with a group of people. Once you catch this, you cannot get rid of it. You have different levels of T.A.D and you will show symptoms at random almost everyday.

"OMG. My mother she..."
"What? What happened?"
"She has T.A.D"
"I- I'm so sorry..."
"No-no it's alright..."
"Just remember..."
"What?"
"The Stanky Leg starts your day, and T.A.D ends it."
"Woah, dude."
"Yeah..."

T.A.D. 

Terrorist Anxiety Disorder - noun

A mental disorder where one lives in perpetual fear of a terrorist attack regardless of location, as if a terrorist will make a bold new statement by attacking a midwestern suburban middle-class house. A person affected with this disorder will commonly hoard massive amounts of bottled water and non-perishable food in their basement in the event of such an attack. These are people who live in continual fear of attacks and still refuse to fly in a plane (thus allowing the terrorists achieve their goal - fear), but can often be found following anyone with a middle-eastern appearance around the grocery store to make sure they are not up to no good.

Will and Sharen suffer from T.A.D. and wouldn't go to the local mall because they believed it was a prime target for terrorism.
