This is called ‘opening a two set’ 
Here is footage of Mystery the PUA doing what he does in the club. Its a mix of offering value (fun stories, dancing, leading conversation), and increasing percieved value (teasing, introducing two competing girls, negging, take-aways, demonstrating higher value).
I would give an analysis for those who are unsure exactly where his techniques are being used (in my humble PUA opinion), but here Mystery breaks it down for us.
Great footage. The analysis that Mystery brings is pretty amazing.
