A Sirius is a person who is so utterly chaotic, their energy cannot be contained. You never know what sewer they’ll pop out of, coming to eat your soul. It’s a known fact that people named Sirius have the best hair, but that’s in trade for the world’s shittiest parents. Is the hair worth it? You’ll never know.
Damn, look at that hair!

Wow, they must be a Sirius!
