Neptune's wrangle 

A high end maneuver during sex where you must maintain penetration, after having blasted your partner in the anus with a dollar store squirt gun filled with the iciest of water.

I pulled a Neptune's wrangle on Brittany and she nearly snapped my dick in half trying to turn around.

Neptune Nugget 

When you wake up in the morning and find your big toe lodged in your significant other's asshole.

I really wish I would have trimmed the nail on my big toe because the neptune nugget I gave Sandy last night caused rectal bleeding.

Neptune Protocol 

A set of rules governing the allocation of beds and the affairs of mating. Where a dude friend has pulled a female on a night out but has no suitable planned venue to engage sexual intercourse with said female, they may invoke this to secure a Host friend’s room and bed for the night.

Kent1: “Who is that?”
Kent2: “Oh, that’s Nat. I hereby invoke Neptune Protocol on your room. Last time I did it in your lounge I got carpet burn and dust mites.”
