What is the verb form of newsjacking? Can I say I'll newsjack on his divorce and make some money. I can't find this in the dictionary, though. Could anyone give me some suggestion? Thanks.
"Newsjacking" is when a brand or firm mentions or creates a campaign centred around a major, well-discussed news item.
So for your example to work, "his divorce" would have to be a well-discussed news item. And you would have to be a brand or firm. You would say "newsjack his divorce" by analogy with "hijack his aeroplane".
Newsjack is a very recent word, and only really has currency among internet advertisers. It isn't in general circulation. Standard dictionaries don't (yet) include it.
