to shit and barf at the same time, a common symptom of the flu; a more crass version of shomit. A shart will sometimes preclude a sharf, so pray that a toilet is nearby.
"Homey, I have to lay off the Mexican food, especially the tequila shots. I spent all morning on the toilet sharfing my brains out!"
To shit and barf simultaneously. Usually done when something foul is ingested or when one has the flu and diharrea at the same time.
Oh shit! I just sharfed everywhere!
It smells like sharf in here!
Who the fuck sharfed in my bathroom!?
If you don't shut up im going to sharf in your bed and cover it up so you crawl in it and sharf in response.
