look up any word, like jamflex:
 
1.
v.- Diarrheading is the act of reading on the toilet bowl whilst engaged in a loose and/or sloppy or complicated bowl movement.

Diarrheading can also be used to describe the actions of an individual who takes an inordinate amount of time in the bathroom due to their enjoyment of their chosen reading materials.
(spoken in frustration and addressing the bathroom door) "I know you drank too many belgian quadruples last night Steve, but you've been diarrheading in there for at least half an hour already"!!!
