sucknis 

Something that cannot be urinated.

Specifically, it's a nonsense word from the famous iCarly YouTube Poop "Freddy Runs Sam's Life", for a sentence-mixed version of a joke by Spencer. It makes as much sense in context, but the line became quite famous for its absurdity.

"Anyone can suck penis, but nobody can pee sucknis."

Person 2: Can you shut up you suckfish.
