Shatomited 

When something is so disgusting/funny/horrible that you both shit and vomit at the same time. (Usually while sitting in your chair or at your computer desk)

Jesus that is so horrible I just shatomited all over myself.

Holy crap, I just laughed so hard I shatomited all over my clothes.

Jesus, I sneezed so hard I just shatomited all over my room.
