A Heather is a name for a stereotype, such as Betty, Karen, Kyle,
Regina, Stacey,
Chad and so forth. If you were to put these stereotypes on a
map, a Heather would be right next to Stacey and
Regina. For further understanding of a Heather see the movie Heathers. A Heather combines the bimbo quality of a Stacey with the cutthroat mean girl quality of a Regina. In fact, where Regina's most notably employ passive aggression, a Heather is much less subtle. If you meet a nice Heather, that is like finding a unicorn that shits 4 leaf clovers.
