1. Someone who evidently attempts to dress as a goth
while being largely oblivious to the actual subculture as they're too smitten by all the nifty black spiky things they can buy to make them look mysterious and nonconformist at Hot Topic
2. Someone who's newly thrust themself into the gothic subculture without a clue as to what it stands for, usually marked by a lame wardrobe, the writing of terrible poetry mentioning blood and broken mirrors at least twice, a newly acquired cutting habit, and several recently failed half-assed suicide attempts.
3. Someone who decides to pose as a goth for no reason beyond wanting to look like a more interesting person, usually unbeknownst to them (the average doom cookie thinks s/he isn't one), but gives themself away immediately with their obnoxious or ridiculously overdone gloomy personality and an unnatural affinity towards being repeatedly raped by Hot Topic's prices in order to own 5 more pairs of bondage parachute pants.
Little pisses me off more than having to put up with that little doom cookie friend of yours.
