Nasty Jack 

After asking your partner if you can unload on their face, get them close close their eyes and instead of nutting, toss a saucepan of near boiling diarrhea (or an emptied colostomy bag) all over their face instead.

Melvin was livid after Big Bob gave his sister a Nasty Jack, especially on her Communion Day!

I was in a small tent trailer with my family. I rolled over because my older sister was standing above me in a t-shirt. It was shocking to be staring at her jacknastyface.

Similar to asstastic, used in reference to a particularly outlandish body part.

Something really incredible and/or truly astounding.

Dude, last night we were at the strip club and the stripper had a jacknasty set of twin towers.
