(v) To prematurely press enter on a Tweet before completing the sentence, most often resulting in other Twitter users finishing the sentence by retweeting. The coinage comes from journalist Mark Hemingway, who had prematurely pressed enter on a tweet starting "We."
I heminated and now everyone's retweeting the abbreviated sentence. Hopefully it doesn't wind up in urban dictionary.
