A bowel movement so great in length that the end of the feces is protruding from the toilet water thus resembling the "Loch Ness Monster".

Get the A Loch Ness Monster mug.
A euphemism for defecating inspired by the Loch Ness Monster. Similar to "dropping off the kids at the pool", yet with a Scottish flair.
Scotsman 1: Good gracious I had a lot to eat last night!

Get the loch ness monster mug.
A gargantuan turd of epic proportions that is long enough to actually stick out of the water like the head of the 'real' loch ness monster. (Must be a solitary log-type poop)

Get the loch ness monster mug.
An extremely long dump that is so large that the head pokes up out of the water in the toilet bowl, while the body remains submerged, much like photographs that claim to show the infamous Nessie.

The key difference between a floater and a LNM is that only the head shows on the water's surface with a LNM, whereas a floater's entire body floats on the surface.
I think I just sighted the Loch Ness Monster in the bathroom.

Dude, I just dropped a Loch Ness Monster in your shitter... where's your plunger?
