Premature Paculation

When you're being chased by a ghost in Pac-Man or Ms. Pac-Man and you quickly turn around after thinking you ate a Power Pellet, just to find out you didn't eat it. You end up losing a life.

This happens more in the higher speed levels because you try to eat the Power Pellet and then eat ghosts as fast as possible.

Premature Paculation DOES NOT refer to the wasting of Power Pellets

Dude: HEY! How come you just ran into that ghost on purpose?

Guy: I didn't mean to, it was Premature Paculation.

Dude: Oh, what's that?

Guy: I thought I went far enough to eat the Power Pellet but i turned around too quickly and the ghost wasn't edible.

Premature Rejectulation

When a user submits a new word and definition to Urban Dictionary and the volunteer editors who happen to review the submission lack intelligence, understanding and/or a sense of humour therefore end up prematurely rejecting spectacularly humorous submissions.

Editor - "A few volunteer editors read your definition and decided to not publish it. Don't take it personally"

Disappointed user - "Damn it, premature Rejectulation again!"

premature redecoration 

Premature Redecoration: Putting up holiday decorations WAY too early.

The day after Halloween as she was taking down {holiday] decorations of ghosts and pumpkins, she put up her Christmas decorations. It's only November first and this is the worst case of premature redecoration I have seen- she skipped right over Thanksgiving!
