look up any word, like cunt:
 
1.
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!

I've got to drop a nessie in the loch!

Scotsman 2: Sounds like a plan, laddie.
