A meme created by 4chan, NOT MYSPACE, that many forums and discussion boards have adopted.

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.

A glorious holiday in which the feline race is celebrated.

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...

The best day of the week. Cats will fall from the sky and you'll receive a thousand sandpaper kisses.

is a contraction of cat Saturday for those too lazy or impatient to use the whole term. Cat Saturday is the name of a blog where they celebrate all things feline.

In contrast to the saturday cats posts on 4Chan, Caturday can also be used to describe any day off. Weekends, Holidays, or simply skipping work usually take place on Caturday.

Implies to be lazy like a cat.
