I think a teaser usually refers to the preview trailer itself, not the person who makes the video. Love the quiz, though. Maybe there’s a good aitch word out there. Or something like a two word option like you did with w! Something like “ate chicken”? Anyway, creative quiz!
I see what happened: "Someone that makes fun" is one part of the clue, and the rest of it is separate. I didn't mean it to be confused as "someone who makes a video" – so sorry about that! But glad you liked it anyway!
