Asstrophy

(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."

testicular matrophy

The slow decay of your manhood after years of matrimony.

I don't know what's wrong doctor. I never get to go out with my friends anymore or watch the game on the weekend. We’re always doing things with my wife’s friends. We joined a book group and go clothes shopping together. Hmm, sounds like a severe case of testicular matrophy to me.

"Did you hear about that kid with Mustrophy?"
"Oh yeah..he's a goner."
