Agreed, arby. I've been gritting my teeth ever since party and parent were verbed. The one exception is Wordie, where it's delightfully enjoyable to roundly mock verbing. Or to verb mocking. Take your pick. ;-)
Making a word into a verb by simply using it that way. E.g. "verbing weirds language." In this sentence, "verbing" is actually a noun. Which makes me wonder if "nouning" should be added to my list of favorite verbs... Hmm... I think yes.
