What does it mean if a guy gently pushes your shoulder?

[Anonymous]

So I'm sitting down talking with my friends at church and this guy that walks pass me pushes gently pushes my shoulder and keeps walking. I didn't look back at him I just looked back at my friends like "what the heck?".

I've nudged a girl on the shoulder while walking with her. It's just instinct. I liked to nudge my shoulder against hers. I guess if I didn't know her at all.. then it'll be different. I wouldn't nudge in that scenario not knowing the girl. But some guys are more courageous.

he wants to get closer to you if you know him if you don't he is just weird.
