A combination of a Fangirl (or fanboy) and a twatmuffin. Generally close minded overzealous fans who - upon realizing they can't win an argument - result to insults and general asshattery.
Guy one: Did you see that guy's rant on how 'awesome' Sephiroth is?
A completely awesome word that should be used by every single person in everyday conversation. A combination of the words "fop" and "muffin," it does NOT refer to a muffin who acts British. In a certain poor quality dictionary, the word foppish was defined as "of, or relating to, a fop." The word "fop" was not present in said dictionary. Though the word originated as a censor to a certain other word that begins with f, its use is almost unlimited!
Dude: Like I was justa chillin' in my crib. ;P
Girl: What the fopmuffin?
Dude: *stops talking for a several minutes on IM*
Girl: FOPMUFFIN!
Dude: Was that said for a reason, or does it just mean "SPEAK!"?
Girl: The latter. :P
