Someone who drifts from social group to social group apathetically with no sense of loyalty or identity. Like a social butterfly, but a little more depressing.

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.
"This place is full of plankton"

"Yeah, lets go"
