The word you are looking for is "snippy," as used when Al Gore retracted his concession. The slang "snappy" is typically an adjective used to convey stylishness, as in "Clyde Frasier sure looked snappy in that jaguar patterned blazer and matching fedora..."
If I'm snippy, its because the "Why are am I reading this" complaint was dumb the first time I read it, and it is even more dumb 15 years later.
