The process of checking one's Facebook whilst on the
toilet. A modern phenomenon, due to the ease of
smart phones. Closely related to Pissbooking (by about
ten centimetres).
After that dodgy
curry, I knew I was in for a big
one. So I decided to do some Shitbooking.
-"Dude, you were in there for ages, you
alright?"
-"Yeah man, just did some Shitbooking"
