globberfluxible 

Used in Mathematics (usually a technical writing class) when Mathematicians try to describe the nature of a function at a certain point but have trouble coming up with a sophisticated example, say "what the hell", throw up both arms and make up a fancy word that has no real meaning, in place as an adjective to the function.

Bad: f is globberfluxible at x = 3;
Good: The function f is globberfluxible at x =3;
