What does it mean when a guy calls me baby that I'm only talking to and not dating?

So there's this guy I've been talking to for almost 4 weeks now and just today I didn't feel to well and I was mad today and he texted me during class and I texted back saying "now not" and he said "NEVVVER" which I'll be honest made me smile and I said "please" and he texted back saying "kk bb" at first I just left him on read because I didn't know what bb stands for. So I texted all my friends and they told me it means baby and I'm over here like "omg he called me baby" So what does it mean if he called me baby?

He's just flirting. Guys do that sometimes same as girls.

No bb is "be back"
Bby is "baby"

Then why is everyone (my friends) and the internet saying it means baby? But the thing is that we sit across from each other and when I say his message i looked up at him and he winked and smiled
