A combination of the words "shit" and "sabbatical." When you have to take a crap and you know it will take a while and you requires some form of entertainment while doing your business. When going "on shibbatical" one might take a laptop, telephone, book, homework assignment, magazine, gameboy, or perhaps a portable television.
"Hey John O, where are you going with your laptop?"
"Dude, I ate a shitload of taco bell earlier, I'm going on shibbatical."

At first I was bummed to have to work that holiday, but then I took a shibbatical in the executive washroom while making time and a half!
