A horrific picture in which a grotesquely "healthy" (fat) female sits. Her nipples are replaced with dicks, which are, well, shitting. I shit you not.
"Her nipples are dicks that are shitting!"
One of the things that 4chan raiders say when they close the pool on Habbo.
"shittingdicknipples shittingdicknipples" repeated over and over again.
