To shit and masturbate at the same time.

For christ sake Jacob you've only gone and shasturbated up the wall .

shasturbate

When one masturbates using their own shat as lubricant.

I couldn't find the lotion anywhere so I shasturbated!

I was wiping my ass and accidentally got some shit on my hand so I decided to shasturbate.
