Why you ask? because my penis is always being tested on by a cold unfeeling overLord and it isn't getting any cake.

Well my GF calls mine a few things >.> Stick Rod Slug Snail. As for her parts she calls her lady bits muffin. Which is commonly used sometimes im sure. She also likes to say azz when referring to her butt. I think thats more beacause of game cencorship in games we play lol.
As for why she calls them slug and snail she likes it when it gets slimey in my underwear from pre and cum. Lol

Dinosaur Empire!

I call My dick my meat rod and my balls my hang lows

I dont have a nickname for it but I guess I can have come up with one. This one called "My Big Black Bold Dick"

Yea sound about right.
