air chat 

like an air kiss between celebrities or strangers, it is a pro forma chat, a chat just to be chatting, without substance. It can be in any format: im, gchat, text, facebook, and even (though more difficult) in person

I met someone last night and I thought we hit it off, but he gchatted me all morning and didn't say a thing. Talk about convo lite!

Did you see her facebook feed? Nothing but air there, all air chat. She clearly had nothing to say but didn't know to stop posting.

When you get hyped in the moment and you begin typing unrealistic scenarios

Dami: Cant wait to go L.A next week!
Elie: Same! I'm going to make a podcast and make 2 million next week soon as we get there.
Dami: Please stop air chatting.
