The act of NASA downgrading Pluto from a planet to a "dwarf planet" (whatever THAT is) prematurely then finding yet another moon orbiting it. The act of premature deplanetation caused all science textbooks and supplemental teaching materials published prior to 2006 to be obsolete. However, with this fourth moon discovery, could Pluto regain it's glory as a full fledged planet?
Joe: Dude, can you believe that Pluto is not a planet? Now I can't teach my kids that mnemonic device "My Very Excellent Mother Just Served Us Nine Pizzas" to learn the planets.
Mike: Don't worry, Bro. I heard NASA is experiencing some premature deplanetation since they discovered Pluto has a fourth moon.

When someone makes an invitation, usually to a home, before checking if it's okay with their spouse. Usually committed by a male.
"Hey, we're here with the chips and dips ringing the doorbell, but no one's answering."
"Oh, sorry it was a premature Invitulation. Not tonight fellas. Wifey said no."

When you retweet someone's link on twitter without reading it, only to realize later it was a big mistake.
Before I read it, I retweeted @Dummy who had a bullshit link about aliens being responsible for the Times Square Bombing...That was a bad case of premature retweetulation.
