Brutal honesty: If a guy approached me like that, I'd think he was either 1) Dumb 2) Insulting Me 3) Trying too hard & not making sense 4) Turn-off
Instead, and I mean this, if you want to get laid & are sick of trying methods that fail (because how can you apply a method universally???) there are a few basic guidelines I can think of off the top of my head.
BADASS YET SECRETLY SENSITIVE WITH A VULNERABILITY UNDERNEATH
-Don't follow pick-up lines, just go with the specific girl & the context
-Maintain an air of "mystery" by not being too eager to please anyone (quiet is different than shy...quiet means simply not having anything to say...shy means wanting to say something but being AFRAID to say it.) Be quiet, since saying things for the sake of saying them comes across as awkward...but try not to be shy...you only live once, and you could pretty much be inside her if you learn how to balance this specific and basic personality & its traits.
