Billie Eilish really needs to react to "WTF IS JOJO (Billie Eilish)" meme so she can confirm to us if that sentence was a JoJo reference or not. And as Ricky Berwick said in this video she needs to know Wtf is jojo for once and for all. 
So let's all of us release WTF IS JOJO memes until she reacts to us !
idk you can use the #wtfisjojo 

Thank you everyone.
