look up any word, like the eiffel tower:
the fun you usually can only achieve in severe cases of boredom. It usually amounts to pain in either yours or someone elses for comedy purposes or to fulfill your boredom.
Car surfing enough said. blowing up frogs enough said.

Hey i'm bored lets do something funstructive i know lets roller skate naked off your neighbors roof into their pool.

Fun + Destructive = Funstructive
Keying your lying, cheating, bastard of an ex-boyfriend's car was both fun and destructive... I must say, it was funstructive.
