I have two one word descriptions:
Specific
and
Vague
What I mean by each is that: I use a very specific definition that defines exactly what 'furry' is, but because its such a broad, general definition, it doesn't really give much in the ways of specifics to me saying something is furry. Its almost as bad as saying "Something to do with the impedance" as an answer to any question about the behavior of a circuit. (Someone like ziel or maybe RY will understand what I mean by this).
