slapnuts 

Additionally, to say "Slapnuts!" in a high pitched voice and slap a pair of imaginary testes on your chin back and forth, while macking a clicking noise with your toungue to imitate the sound of the nutss being impacted by the palm.

Used for when you have nothing better to say.

As Bob and Jorge sat around bored, Bob said,
"Slapnuts! Ktch ktch ktch ktch!"
Jorge laughed, then went back to being bored.

Bob later overdosed on sugar.
