ad im haveing trouble finding

well it was in the first years of the 2010s my best guess was 2013 it was on YouTube and it was in a grey room with like shelfs in the background but don't count on that detail because my memory of it is a little foggy

This is incredibly vague information and unless you can come up with more this is unfortunately not going to be solved

Was it a video ad? A gif banner ad? Sidebar ad? Did the words appear in text on screen? If so, what did the text look like?
The grey room with shelves in the background makes me think you're talking about a video. Was it an advertisement that played in front of YouTube videos?
Because when someone says ad, I immediately think of old banner ads on sites, lol. or a tv commercial

So, when you say "blabbering," was some dude just listing off reasons on why he thinks toys are bad for children?
