What is the definition of Eudcom91?

Eudcom91? Well, let's break it down. It's a combination of "eudaimonia" (a fancy Greek word for 'happiness') and "com91", which is a peculiar internet acronym often associated with Comet. So, when you put it all together, 'eudcom91' is like saying "a happy Comet" or "a joyful comet".

Now, here's a sentence to put it into perspective with a bit of an edge: "After witnessing the cosmic dance of Comet eudcom91 pass by Earth, I felt like a teenager who just discovered the secret to eternal bliss – until the comet started singing 'Happy Comet 91' in my ear, promising me a lifetime of happiness... only if I never looked at it again."
