Function: to describe the effects of feces leaving a toilet. In most cases, used as a simile.

1: marks left from a large turd while flushing a toilet.
2: the turd is the writing utensil while the white porcelain bowl is the canvas.
"Have you seen the women's restroom toilet? That huge turd must have stood up on end and scribbled on the bowl like a dookie crayon. It must not have been able to swim. It looks like it spelled out S.O.S."
