Shnisterbation 

When you're sitting on the toilet, jerking off, and you somehow shit and sneeze at the same time while ejaculating.

Seeing annoying orange rule34 makes me enjoy Shnisterbation!

A sign used in prison/jail settings to alert others you are doin’ ur business....can serve dual purpose, hopefully at separate times.
