The act of needing someone to take a shit on your chest in order to be able to function (i.e. at work). Very similar outcome to the Cleveland or Boston Steamers, but the fuser steam enables those afflicted with it to perform at their given tasks; without it, they feel otherwise incapable of functioning.
Can be likened to an OCD (obsessive compulsive disorder) affliction, resulting in the afflicted being somewhat addicted to the task.
"Dude, I can't get any work done until a get a Fuser Steamer... just doesn't feel right without one"
