Nut Shell-shock 

The act of beating it so hard, once you finish it is hard to concentrate on things other than what you were doing.

Person 1: Hey did you watch the game last night?
Person 2: Huh..? Sorry I'm in nut shell-shock right now.

Nut Shack

When you do a Franklin Creamer in a porta potty.

My day couldn't get any better. On my way to the bathroom I found a fresh turtle! Looks like I'll be making a nut shack today!

Nutshock 

When you nut so hard you become disoriented and your ears start to ring.

"Dude, I just had some of the craziest nutshock last night."

"Gnarly brah."
