A Wikipedia vandal, who is notorious for placing signs which block text and replace it with Pelican Shit or some variation on that using poorly written CSS and HTML. Has over 900 sockpuupets. More can be found @ Longterm-abuse on Wikipedia.
Googling ass pus, spongebutt squarepenis and pelican shit will show most of his handiwork.
One day, I looked up something on wikipedia, and written in a colorful table at the top of the page was:
This page fucked up by
*** PELICAN SHIT PRODUCTIONS ***
Got Ass Pus?
And when I scrolled down it didn't move, so I refreshed the page until it was fixed two minutes later.
The shit of a pelican, dumbass.
It's pretty much self explanatory: Pelican Shit.
