That's a good question. I'll have to get Rachael to write up a good definition of it. Basically, a retro-zombie is a cartoon charater that Rachael dreamed up so that she can torture someone. They're based upon a group of people at her school whom she can't stand. Basically, those people are skater-preps with no fashion sense whatsoever. However, even if you are a skater-prep with no fashion sense, that doesn't mean she hates you. Her hatred is reserved for those people (you know who you are) that she personally knows. So, there'll be no need to contemplate suicide because you think Rachael doesn't like you.
