I don't know why, but "trending" as a verb really irks me. I have a nice Oxford Dictionary made out of actual paper and in it "trend" is only
a noun. I guess it shouldn't bother me. I almost feel like a hypocrite.
I make up words all the time. I even have my own gerund-speak. For instance, if I want my husband to grab something that I am handing to him, I say, "Taking." Or if we get on an elevator and he is distracted I would say, "Pushing." Actually, gerund-speak has a slight hint of a question mark behind it. As in, "Are you going to push the elevator button?" But I would never, ever, under any circumstances, show him something that is cool and happening and say, "Trending."
