Post Function. The event that immediately follows a party or event. Includes only a sub-set of original attendees. Typically this is the primary source of embarrassing tales of debauchery and over-consumption of alcohol; however, it not to be missed. See afterparty. Derived from pre funk.
Mike: Holla, holla y'all. Post Funk at the Ironhead!
Matt: Word, yo! That place is off the hook!
(The two, and accompanying friends proceed to the aforementioned watering hole)
