neptune's kiss 

The splashback of cold bog water up your ringpiece when dropping the kids off at the pool.

(from cubicle): "Aaaaaah"
(from other cubicle): "Neptune's kiss?"
(from first cubicle): "More of a peck on the cheek."

Neptune's kiss 

A Neptune's kiss is the splash of water that touches your butt after pooping in the toilet. The Neptune's kiss is basically your shit kissing gou goodbye

"took a dump so big I didn't even need to clean myself afterward: the massive Neptune's kiss resulted did the job"

Neptun's Kiss 

The same as backsplash.
Hugely annoying.
Can be avoided by clever usage of toilet paper.

"Aieeeh!"
"Whut?"
"Neptun's Kiss, man."
"So what?"
"The water's effin' freezin', man!"
