Often abbreviated C.F.; Congress Fatigue comes when you stay in one place for too long. When suffering fro C.F. you exhaust all your resources (resources being your "Favorites List") or adding too many episodes of Hoarders to your TiVo. When one has done all this they suffer C.F. ever worse thus making them go into a rut that is damn near impossible to break. This can lead to the much worse, Cabin Fever. One can imagine this being felt by the actual members of Congress.
Charlie: Damn computers was brutal today!
Steve: I know! I didn't do anything but go onto my favorites list and I was still gettin' Congress Fatigue.
Charlie: I didn't do anything but use my phone to schedule Hoarders on TiVo.
