What does it mean if a guy stands really close to you while walking?

So me and him have been friends for a year now, I like him a lot but nothing has ever happened we never dated. Alto we do talk everyday and chill everyday and smoke. I should mention we did have sex once when we were drunk and high but that never happened again nor did we talk about that again. So today as usual we met up and chilled to smoke and when we said bye to each other as usual we walk from the place we smoked to our on ways and when we were walking at first there was a big distant between us but then he moved super close to me like super close and we walked like that. (So close that I don’t think friends do that) is it normal to do that with a friend going from walking far to super close to each other? Or is that his way of flirting?
