(noun)- a turd of mythical size. The base stays hidden in the bowl, while the head is the only thing that is seen. If you do not snap a picture of it....people may never believe it happened.

In addition to its length, circumference, and overall gargantuan stature, these often become what are also known as "bowl stainers." Leaving behind a mess that...well...isn't human.
Brother: Dude, I just took a two foot bowl stainer and no one was home to see it.

Other brother: I don't believe you.

Brother: Damn! Another Loch Nessie Messie....
