Pygalgia

It’s a noun occasionally used in pathology meaning a pain in the buttocks. So if you say that someone gives you pygalgia you are saying in a polite and technical way that they are a pain in the arse.

“How would you describe Malcolm?”
“Pygalgia!”

Pygalgia

Originally a medical term used to describe the pain associated with piles, now used to describe someone who is a pain in the arse. See also rectalgia.

Malcolm must think the boss is suffering from piles, he's got his head so far up the boss's arse it's a suppository.
I don't know about the boss, but Malcolm gives me pygalgia.
