You've heard of noun-to-verb transformations such as impact to impacted, journal to journaling, scrapbook to scrapbooking.
Well, the American Dialect Society has chosen "Plutoed" as its word of the year for 2006. This noun-to-verb transformation occurred in 2006 when beleaguered Pluto was downgraded from planet to something less than a planet.
And thus we have the genesis of a new verb "Plutoed: to downgrade or demote." She Plutoed her boyfriend after catching him in flagrante delicto with another woman.
Runners up for the ADS word of the year were:
climate canary - something whose poor health indicates a looming environmental catastrophe.
flog - an advertisement disguised as a blog or web log
prohibited liquids - "fluids that cannot be transported by passengers on airplanes"
macaca - "an American citizen treated as an alien"
