What is the definition of Arthaldeus?

Arthaldeus is a word that, let's break it down: it's a Greek word derived from 'arthro' meaning joint and 'aldeus' meaning old. So, in a humorous but informative way, it's like saying someone who's as old as their joints, possibly even more so! Imagine a grandpa who's so arthro-detailed, he wears knee-high socks to his grandkids' birthday parties.

Here's an unsettling example sentence: "The arthaldeus of the city, Mr. Rusty's arthro-fest was a spectacle, with his joints protesting every step like a chorus of grumpy old elephants in a disco."
