You thought Peeps were just marshmallow chicks, right? Well, clearly you haven't read Scott Westerfield's YA novel,
Peeps, in which the titular designation refers to those people who are "parasite positive." In Westerfield's world, peeps are human beings infected with voracious parasites that compel their hosts to transmit said parasite through blood contact. With hopped-up, superhuman senses, long lifespan, bloodthirsty instincts, perpetual horniness and aversions to sunlight, peeps are most commonly referred to as -- you guessed it -- vampires.
