Would it be weird to Facebook message a guy I met at a bar the other night?

Anonymous
I was pretty drunk so I don't really remember how our conversation went, but I got his full name and found him on Facebook. I think he's very attractive and I really missed my opportunity. How weird would it be if I messaged him? If I just say "hey we met at the bar last night and I didn't get a chance to give you my number. It's ##, text me if you ever want to get together." Would that work? I'm pretty game for just fooling around so I don't want to make it seem like I'm just asking him on a date.

oh the other issue with that is the message goes into his other folder so he might not even see it. I know I don't look at that. So do I friend him? Or just send it and hope for the best? I feel less ok about adding him as a friend haha
