This video is funny, but one thing it isn’t is trolling.
Or at least, there’s no evidence of it being trolling. Trolling means provoking a negative reaction for your own amusement or rhetorical purposes. Making other people laugh at silly book titles is not trolling. And that’s all the video shows us: other people laughing. I might guess that at least a few of them were in on the joke, especially since this is the second such video.
Get your nomenclature right, internet!
