I just noticed a side-ribbon flyout of YouTube that, when the logo is clicked, expands to ask "What would you like to play?" I don't recall adding any extension to Google+ or Chrome that would add this. What is it for? Can it be removed?

Similar to the Facebook inspired Ticker meme

I am afraid there is no way to prevent/remove it that I am aware of, I will look out for extensions in the meantime.
