Less vulgar and more entertaining term for "Mother Fucker";
instead of Fother Mucker, "Father" is used to confuse the listener.
See also: "Nucking Futs" Same methodology used.
<Shinosuke> It's "Pronunciation", not "PronOunciation"...
<Shinosuke> You stupid Father Mucker!
* Shinosuke grins and acts all smart and mighty.
