Yotsuba comes from the Japanese [[manga]] ''Yotsuba&!'' (from the guy who also writes ''Azumanga Daioh''). In this comic, she is an adopted and naive and energetic five year old girl who doesn't understand how anything works.
She started being referred to as 404 Girl when one possibly [[troll]] [[anon]] asked [[b/|/b/]] for [[rule 34]] on the 404 girl. This post occurred in April of 2007 and led to numerous [[facepalm]] jpegs. This rule 34 was instantly considered taboo, and thus many trolls have since repeated the request.
The responses to these requests almost always include:
*I guess this is why they call her "404 girl" ROFL xD
*[[cockmongler|lol hey look guys, its smiley man!!]]
*xD xD xD xD xD xD xD xD xD xD xD xD
*OMFG SHE IS CALLED YOTSUBA!!!!11eleven
Naturally, as a response to this meme, much Yotsuba Rule 34 has since surfaced. , much Yotsuba Rule 34 has since surfaced.
