(1) Atrophy of the ass.
(2) Extreme weakness of the buttocks.
When sitting too long, the buttocks can become numb and the butt muscles can stop working properly therefore resulting in what is known as 'ASSTROPHY'.
"Dude! I am totally experiencing asstrophy right now."

"Apparently he had to quit working as a truck driver because it gave him asstrophy."
