Closing is made easier by being physical early on. high fives, hugs, claws, gay shit like thumb wars, picking them up. Stuff like that. People form impressions of each other pretty quick, so its helpful if you make a point of being a dominant, physical dude.
The two main things are that this is done in a way that's both FUN and DOMINANT.
By fun I mean have fun, don't creep. Smile, laugh, chuck her in the sea, whatever.
By being dominant I mean take the lead and do this shit strong. No dancing round it, no 'waiting for a signal', and definitely none of this

Do this early on and closing comes extremely natural.
