This song is making a joke of how lots of YouTubers use Christmas to fish for views. He mentions how they use clickbait to get likes and views, so they can make more money from advertisers. Usually, they use thumbnails and titles to persuade people to watch the video. For example, a YouTuber would make a video about Christmas shopping and title it MY HOUSE FELL DOWN?!?!?! emotional with a thumbnail of them making a face.
