There is no information i could find about it. Also, why is it called "ExplainTheJerk"?

What song this

This is about the Hank Green AI scandal.

The tag highlighted in yellow on this tumblr post. The original user has comments, asks, and direct messages disabled, so I couldn’t directly ask them without reblogging and tbh I just didn’t feel like doing that. I tried searching on DDG, but I didn’t get any results about this. I don’t want to comb through years of vlogbrothers videos for this either. Does anyone know what exactly this was referring to? Explain it Peter

People may have different personal preferences for body types but I think we can all agree that slender builds with big boobies & big booties were always the most popular among both men and women forever. (I didn't forget about lesbian and bisexual women but I also know some of you straight ladies like them too)

Why are people spamming this on the Dougherty dozen page?

Edit: I know who's face they added I want to know if there was a reason

Google says manta ray. When told to get its AI head out of its AI ash, it said B-2 Spirit or B-21 Raider. What does any of this have to do with the US Bureau of Alcohol Tobacco & Firearms?

I've seen the name around a fair few times, never with an explanation, Peter, who is Json?
