An acronym for "Please Help Us Kidnap." The origins of PHUK date back to 2010 when some Cape Cod locals decided it was dumb as shit that a few fun hating conservationists (terrorists of summer) were causing the beaches to be closed for weeks and months on end due to a few nesting shorebirds that just happen to be endangered. Thus, PHUK Plovers emerged as an obvious solution to unite those who care to PHUK and return some semblance of sanity and reason to the people.
Used in context, i.e. "PHUK PLOVERS" is a call to action for people to stop standing by idly and start kidnapping this small avian species so we can all get on with our summer festivities and lives in general.
