Just as Aquascoot's 'nasty' woman just flirts her way towards getting free drinks and meals.
So too do men 'deceive' and get free sex by 'nice' women.
You can get anything you want if you con, lie and deceive, etc.
I knew one guy who picked up women from just looking at their lips all the time. Good for a 'short-term' FIX. But nothing to really throw the responsibility of a long-term and 'real' relationship on.
Then there is the addiction of 'short-term fixes' for sex, where - in time, such people can NOT step up to the long term relationship.
Many MRI scans have shown the brain 'grow' in part, for those in Long Term relationships. The 'commitment' I guess commits to continued growth.
Where-as the promiscuous people have no growth at all and also tend to be people you can't rely on in the work-place: lack dedication, commitment, etc.
I've worked with guys who 'just root around' - the work like 'Tools'
Take the Black North American Man and the Grey (Raven haired rock star) North American Man. The so-called 'Wankers' of USA Society. All about sleeping with as many women as possible (but never breeding as well as the Rednecks) and even shagging the President's wife.
They both end up in dead-end pleb jobs (if they make money - they are usually alcoholic, drug-addicted) and living on the street inside a card-board box with a glory hole.
So Pick Up lines only go so far and are mostly just used by the promiscuous playing 'the game' for the slutty women who are easily swayed by 'simple words, used for the occasion' only.
I've never been bothered with being wily with words to get girls. It's like wearing a shirt that isn't mine or pretending to work a job that I don't really do - just to impress.
Such people who 'play the game' are mostly shallow, superficial, uncommitted, selfish and eventually boring.
