Word used to describe utterly detestable and braindead peasant underclass. These are the slutty, often chav bitches at parties who you wish to kill slowly. However, despite appearances, there is a reason for their existence. Their sluttish antics (such as false lesbianism) distract the male equivalent of plankon, thus reducing 'competition' for the more discerning male.

Plankton are simultaneously a disease and a cure.
