Quibble 5? Oh, I'm all up in it!

I adore words and enjoy taking them out to play and build things. I like new shapes, textures and colors.
Sometimes, though, words or phrases begin to stray toward cliché just a little too quickly.
Maybe the first time I heard the following, I found it cute. Maybe it even amused me or struck me with its fresh vigor. Drum roll, please. How many times have we been subjected to, "I'm on it!" or "I'm all over it!" as the side character dashes off to save the day without so much as a grunt in response from the captain/commander/nut job in charge?
Is it the repetition or merely the ever mutating, lemming-like qualities of what makes our language wander into the weird and wonderful and faddish that turns a word or phrase into a quibble? You never know when one of those new words will assume it's rightful place in the latest edition of our legitimate lexicon.

No worries, though. We word lovers will remain grimly enthusiastic and "all over it!" when the time comes.
Cheers!
