first used on the hit film 'your highness' as a term to describe a fuck that would happen when two moons became one. an event that would spawn a dragon baby.
Fuckening is the ritualized taking of someone's virginity to become a more powerful being. It is best done under the light of a full moon with spectators in dark robes.
Brad: Hey your looking fierce bro, whats up?
Ned: Julie and I took part in a fuckening last night I feel great!
Brad: HIGH-FIVE!
