Sorry but i find this another complete bullshit phrase in the 'Pua' community just as much as i hate things like PUA, HB, AMOG, -- i think its laughable

Ok so you 'pickup' a nice girl (not a slut) use your magical 'Pua' powers and end up 'Fclosing' her -- she then says she really lieks you but you say ohhh i dont want anything heavy.
she feels used and you wander off onto the next bird

leave her better than when you find her..what a total load of shit

thats fucking people justifying to themselves why what they do is acceptable
