I hate it when nouns are converted into verbs.
There's no such thing as a noun that can't be verbed or a verb that can't be nouned!
Second:

"I say to you"..
"At the end of the day"...
"Step up to the plate"...
In context any of these are OK, it's just that they are used out of context and ad nauseam to become cliches. The "step up to the plate" is an American idiom derived from baseball, where the next hitter to come between the pitcher and the backstop steps up to the plate to hit.

'Driveway' instead of 'drive' and 'park up' instead of 'park', and all the other similar horrible American elongated words.
You have to remember that for quite a long time now American and English have been different languages, albeit only slightly. Both are living languages and drift all the time. I don't see this as a problem.
Finally, my own contribution to the debate: Summary/Summery. I sometimes work in a place where there are summaries of notes. Someone who works there continually writes the word "Summery" on notes which still need summarising. I have pointed out that this means that they are sunny, warm, and only applicable between June and August, as opposed to "Summary" which in this case means that they need a summary, but it falls on deaf (ignorant and extremely irritating) ears.
