A meme created by 4chan, NOT MYSPACE, that many forums and discussion boards have adopted.
Caturday is a fun day because cats with text below them make me laugh.

The greatest holiday on the internets. A day to celebrate the greatness that is Felis Domesticus, or the common house-cat.

Despite popular thinking, LOLCats RIPPED OFF the meme from /b/. Not to say that it wasn't a stupid thing to begin with, but still...
You know what day it is? Do you?

It's Caturday, bitches.

So get off of your assess...

...and post some fucking cats.

A glorious holiday in which the feline race is celebrated.
"Mom, how come there's a mother's day and a father's day, but no caturday?"

"Every day is Caturday."

Two Saturdays of every month in which the majority of the day is spent photographing one's cat to later post those pictures on a myspace bulletin so that people may comment on them. Sadly, men also participate in this activity as proven by the originator "Chaz". In short, it's pussies taking pussy pictures of pussies for other pussies to post pussy comments on them.
Craig: "Have you seen the latest Caturday pics on my bulletin? Comment on them, won't you?"
Derek: "Get away from me."
Jader: "lol"

Though the origins are fuzzy, Caturday was spawned on one of the many *Chan image boards by the user Anonymous. On every Saturday, you post cats for lulz.
