Io

Io is unfathomably large; it is said the largest dragon who ever lived is smaller than a single one of his scales, which are blue, gold, brass, or red, and edged with silver and dark purple. He can, and does, appear as any age or breed of dragon, however.

Mostly used to replace other gods as if to avoid being offensive

Person A: Hey dude, did you finish your homework last night?
Person B: Oh for the love of Io, I forgot.

Io

Piece of garbage that no one likes. Everywhere they walk curses the earth and the people around them. They deserve nothing, people lending them a hand and yet they’re still terrible to them.

Wow you’re such an Io

.io

A game genre that originated in April 2015. It all started with Agar.io, a game where you have to eat like a pig and try to become the biggest player in the server. Not long after, Slither.io was released, followed by Wings.io, Diep.io, Splix.io, and many more.
Due to how simple they are to make, there are hundreds of .io games out there.

I remember when the first .io game was released.

Yeah...and the creator was...19 at the time? He probably thought his game would fall off the face of the earth...but instead he created an entire genre!
