Was this guy hitting on me? Or could be something else?

I was at a bar. Guy was sitting on the right of me. I looked at him and smiled (meant in a friendly way). He said "good smile" and moved to seat next to me (he was one away). Then asked for my number. I was drunk gave it to him. While we were there he texted me randomly, you want to f** around tonight? I just chatted with him but he texted me hours later at like 2 am.
