Reference to Joe Goldberg what does it mean

So my crush requested me on insta and after we spoke I said wait how did u find my insta and he wrote think of me as Joe Goldberg. What does that reference mean?
And then when I said I’ve never really spoke someone this much cus I’m pretty quiet he was just like so I am special, and I said ig. And he wrote I’ll take that as a w 🤞
