It means big fat gooey watery fart that makes you feel energetic and happy like a unicorn on cloud nine
Bro i thought i did a normal fart but it was an actual Nessy!
The most gorgeous woman in the world. Her eyes are captivating, that face is also the cutest ever. And her body is so f*cking sexy you can't even believe it. She is the woman you'll want for yourself, bc her heart is the biggest and her soul is the kindest. She is simply amazing.
Nessy is the most beautiful
A messy Nessie is when your poop is so long that one end of it is sticking out of the toilet water like the head of the Loch Ness monster
That messy Nessie was so long that it almost touched my butt
When left with no other option, one hastily rushes into a lake to let go a mythically proportioned shit. Resulting in a bobbing turd monster that people confuse as a cryptozoological beast.
As I was running with my toddler to my mother-in-laws house to dedicate, I was left with no other option than to jump in the lake and let loose a messy Nessie
When your homie smells like 3 day old bong water.
"Damn, Sharon over there smells like a hot messy nessy!"
A standing turd in the toliet, partially above the water line.
I just took a Bowl Nessie in the toilet.
