404 Girl

404 Girl is the nickname people have given to the girl on many of 4chan's numerous 404 pictures, which come up when you try to refresh a thread that died while you were away. However, weeaboos, faggots and retards will call her Yotsuba. /b/ is limited to keeping 15 43 pages worth of active content 'up' after which a dead or dying post will go to the post graveyard.

*Note: If a weeaboo calls her 404 Girl they fail (moreso) as one, because her name is Yotsuba (meaning four-leaf, GET IT? LIEK 4CHAN! HA! HA!).

404 Girl

The name originated when either a newfag or a troll posted to /b/ in April 2007 requesting Rule 34 on the 404 girl. The request was met with a barrage of facepalm.jpg and dubbed the failest post to ever fail. Despite being the sick fucks they are, Anonymous has decreed that making Rule 34 out of Yotsuba is taboo and the penalty is an IRL Banhammer. This is ultimate proof that even facepalmers are capable of faggotry themselves.

For the love of God, HER NAME IS YOTSUBA PEDOBEAR MATERIAL.
